Sales are pretty good, only a few new games on sale for non-Kinect owners, but that's much better than what we've been getting. I was gonna reply to a bunch of people, but instead here's my take on some of the games, if you're interested:
Castle Crashers - Has been discussed to death on this thread, but it's probably worth 600 if you've never checked it out, but (to me) it was pretty standard fare beat-em-up. I can't imagine that it would be much fun in single player at all.
Trials HD - Has also been discussed to death on this thread, and most are really torn on this one. I don't want to start anything, so I'll just say check out the demo and see if it is for you. Keep in mind that it gets WAY WAY WAY harder, to a controller-smashingly hard difficulty level. Personally, Trials isn't for me, but check out the demo for yourself because there are TONS who love this game.
Iron Brigade - Another one that is way better with friends or at least randoms online (no local MP). I'd say the single player portion is still worth 600 easily and it is a fun game, but it gets a little monotonous and frustrating solo. This is because there are lots of spawn points on a lot of the maps, and your Trench vehicle is slow as hell. A good amount of customization within the game, though the currency in the game seemed to be 100% worthless. The DLC is apparently more of the same (and from reviews, extremely difficult to complete solo).
Orcs Must Die - Ironic that this is on sale the same week as Iron Brigade, because it's another tower defense game that just feels like it was built with MP in mind. Problem with this one is that there is ZERO multiplayer options. 600 is the max I'd recommend for this one as well, it can be fun but just as frustrating as multiple spawn points means lots of enemies sneaking into your base behind your back.
Fusion: Genesis - This is a weird one. It's a twin stick shooter set in space, but you get missions and tasks assigned to you. I've only put in about an hour, and it can be really overwhelming with all the menus, items, customizations, leveling, and factions that you work with through the game. I'm not 100% sure I understand the game yet.
NEXT WEEK'S SALES:
Outland - Awesome game. Well worth 400msp. Best game of the 2-week bunch!
BG&E HD -

ed up camera controls if you play inverted. Haven't gotten into the actual game yet, not really a lot of ambition to do so because I'm gonna have to re-learn the camera.
