There’s a pretty wide breadth of stuff here. On the Downloadable Content side, you can shore up your copy of Sonic Unleashed with new stages and missions — all of the various Adventure Packs for Sonic Unleashed are discounted, with tons of daytime and nighttime missions. I’m a big fan of the daytime stages, and all of the available packs feature more daytime than nighttime missions (but for Werehog fans, there’s plenty of nighttime missions as well).

Speaking of Sonic, the “very hard” missions for Sonic the Hedgehog 2006 are also discounted, so if you were ever looking for a dirt-cheap excuse to complete your Sonic collection, there you have it! But the real gem — at least in my own humble opinion — is the extra content for Valkyria Chronicles. This includes all three DLC packs, featuring bonus missions and the amazing EX mode, which has a ton of new features, weapons, and increased difficulty.

I’ve already written lots about my undying love for the tactical strategy of games like Shining Force, and Valkyria Chronicles is absolutely the spiritual successor to these games. While I can’t say enough good things about the game itself, I also am incredibly impressed with the DLC that’s come out — it’s not just an ad-hoc collection of maps or standalone missions, but several new ways to play the game that deepen and add to an already complex and emotionally engaging story.

Don’t just take my word for it though — our own honorary Gallian, Ruby Eclipse, has fought long and hard for this game as a labor of love. His message to the fans who have worked so hard to help make this great game succeed:

To arms, Gallia! In support of the season and our fans’ amazing dedication, we’d like to say thank you with a special 40% off holiday sale across all three packs of Valkyria Chronicles DLC!

See the battlefield from Selvaria’s eyes in Behind Her Blue Flame, take on challenging odds with some of Squad 7’s rising stars in Enter the Edy Detachment, or add a whole new level of difficulty – and earn new, powerful weapons – with Hard Mode EX!

Did I say PSP games before? Oh yes! A little while back the community team here at SEGA took a look at some of the best & brightest PSP games SEGA had made, in celebration of the launch of the PSPgo. Now those titles are slashed 40%, and it’s nigh time to take a look at shoring up your collection of portable games.

I already wrote about Sonic Rivals, and now both Sonic Rivals and Sonic Rivals 2 are part of the Holiday sale. This was an awesome experience — I hadn’t actually played them until recently, and didn’t really know what to expect. I was surprised to find that these are incredibly well-crafted racing games, but with the exquisite level design that’s always been core to the best games of the Sonic series.

Aside from the great Sonic games that graced the PSP I’m thrilled to say that some of the most eclectic and unique titles ended up on that system as well. I am speaking here of the incomparable Crazy Taxi and Crush. Crazy Taxi is exactly what it sounds like, and this is a very good thing. It’s also good that it’s on a portable system, because this is one of those games where one’s body tends to move in direct proportion to the craziness of the game as you twist & turn your way through crowded city streets.

This really just scratches the surface — you can also pick up the gnarly road-battler Full Auto 2: Battlelines, the charming & addictive Super Monkey Ball Adventure, and the awesome 2D action shooter, Gunstar Heroes!

Alien Syndrome
Alien Syndrome is a sequel to an old arcade game of the same name and takes place some 20 years after the original. Featuring over 80 different weapons, hundreds of armors and items, 3 difficulty modes, ad hoc multiplayer, and over 40 levels, Alien Syndrome will keep any dungeon crawler busy for a while. The game is probably best described as a top down shooter with added RPG elements.

Crazy Taxi: Fare Wars
Are you ready to make some crazy money? Crazy Taxi for PSP is actually a collection containing the original Crazy Taxi and the sequel, Crazy Taxi 2. In Fare Wars, you’ve got access to all the original crazy moves, over 30 crazy mini-games, and crazy modes you remembered from the original games. Added bonuses include a customizable soundtrack based on your own music from the memory stick and local multiplayer games in head to head battles. We’ve had some fun replaying this in the office and it’s a welcome addition to anyone that’s been looking for a Crazy Taxi fix.

Crush
I’m a huge fan of Crush and think that every PSP owner and puzzle fan should check out this game, it’s just that good. Crush uses a unique concept, taking 3D environments and “crushing” them into a 2D plane. Since the environment is in 3D, you’ll have to rotate game world to find the best places to crush and gain access to different areas of the level. Need to get atop a ledge, but can’t jump to it? Simply look top down, Crush, walk over to the ledge, unCrush and you’re where you need to be. The challenge then comes in working with the basic rules of the game – for example, some blocks you can or cannot traverse in the 2D plane, but can’t get across in 3D, or vice versa. If you missed Crush before or just want to replay it, now’s an excellent time to pick it up.

Full Auto: Battlelines
If Crazy Taxi is a bit too tame for your racing needs, Full Auto Battlelines might be the fix you need. Full Auto is all about car combat, destructible environments and an ‘unwreck’ ability that allows you to create opportunities out of mistakes. Unwreck is, like it sounds, an ability that allows you to escape a bad decision and rewind time to avoid that bad turn or unexpected hazard.

Sega Genesis Collection
If you are a Sega fan and want some game to satisfy your classic game lust, this is the title for you. The Genesis Collection features 28 games and 5 unlockables, including favorites such as Sonic 1 & 2, Phantasy Star series, Shinobi, Vectorman 1 & 2, and the Golden Axe series.

Iron Man
Based on the blockbuster, Iron Man PSP gives you the chance to head into battle as Tony Stark within the Iron Man suit. If you are familiar with the basic plot of the Iron Man movie, the game is essentially the same with a few additions, including new encounters from other Marvel villains within the Iron Man universe.

Sonic Rivals & Sonic Rivals 2
Sonic Rivals is a different take on the normal Sonic the Hedgehog experience you might be used to. Rivals is best described as racer, you compete against other characters from within the Sonic world, pick up powerups, tackle bosses, and fight to stay at the front of the pack. Bosses? Yes, there are some unique play ideas at here that have you competitively and cooperatively downing bigger enemies. On top of a solid game, you’ll also find unlockables cards that give you some insight into the past Sonic series.

Super Monkey Ball Adventure
Monkey Ball for the PSP actually comes in a different style of game than the previous series additions. You play not only Monkey Ball puzzle stages you are familiar with, but also play in larger open world areas with platforming, missions, and mini-game, hence the Adventure name.

As noted, back at the Sega Blog, we’re doing a bit of additional coverage on the PSPgo titles. Some of us are revisiting old games we enjoyed; others are picking them up for the first time. Head on over and read my write up on Crush and look for new blogs about some of our other games in the days to come.
