I know you’re excited about that New-fangled Xbox Experience that came out today. You can’t wait to get lost in this strange new maze of bright icons and non-demarcated advertising. But after you’ve given your avatar your dream porn ‘stache and reveled in Netflix on the Teevee (now free of that Sony Pictures stink, apparently), try to cut through the clutter and find the real prize of the Experience: Community Games.
Surely you remember Community Games. That’s what Microsoft is calling the indie games service that got a big reveal at GDC 2008 before disappearing completely from view. It’s out now, but it’s still hard to find; on my 360 it’s five deep into the Game Marketplace menu, peeking out from behind some Gamerpics of Lebron James (and even that’s not the whole list—to get to that you have to go to Games Marketplace, then Explore Game Content, then All Games, Browse, Collections, Community Games).
We’re talking real, true indie stuff here, not that polished, “I have a big three publishing deal and an interview on newsstands now” product that people have been calling indie. This is gritty, garage band gaming, warts and all. It’s pretty exciting to see this sort of thing on console, so I’m going through as many of the free trials as I can. Below I’ve picked out a few of the gems you should try, if only so you can say you liked them before they sold out:

Artoon: Part puzzler, part platformer, this game uses sketch-like shading (think Valkyria Chronicles) and looks great for it. Some interesting use of space in the puzzle design makes this worth a download.

Biology Battle: A perfectly competent multiplayer Geometry Wars clone with a tenuous grasp of English that makes the whole thing even better. It’s a shame it costs twice as much as the game it cribs from, though.

Colosseum: An ambitious stylized 3D arena fighting game. This makes for a pretty good technical showcase of what an independent developer can do using XNA, if they really try.

In The Pit: You are a monster that lives in a pitch black pit. There are no graphics in this game—instead, you use audio cues and vibration to find and eat the people that fall in. If you have a surround system, try this immediately. It’s the kind of creative madness that only a completely independent developer could come up with.
Weapon of Choice: Now that’s what I’m talking about. This one’s a charmingly low-budget Contra-alike that’s got strange, awesome weaponry and some pretty interesting design ideas.
