We know it’s a crowded year, but between Halo 3 and Call of Duty 4, there’s no reason not to pop in one of these criminally ignored online enabled and give them a go. If you’ve never played them, here’s all the reason you need.

-Lost Planet: While it’s single player campaign was short, no one seemed to notice the inventive mutli-player gameplay buried inside this one. The grappling hook was a wonderful variant that made the spectacular level design easily utilized. Vertical areas were always fought over, and there was a reason for it. Once up there, you could dominate, but only if you could fend off those fighting for the same spot.

-Puzzle Fighter HD: While it’s not hard to find a match, there simply aren’t enough people playing this brilliant Capcom puzzler. It’s the epitome of versus gaming and arguably the best game on the Live Arcade, requiring skill, thought, and the right amount of luck so you’ll never feel cheated if you lose. The remixed character stats from the original version from the arcade make this rebalanced affair all the more tempting to any competition seeker.

-Crackdown: Once this Halo 3-beta containing game became obsolete, so did the awesome co-op play. Not many people realized how much more there was to do aside from take out bad guys. However, the amount of modes you could make up on the fly, from rocket launcher dodging, impromptu racing, and jump challenges made every co-op run a memorable one.

-Chromehounds: From the moment is released, Chromehounds grabbed a hardcore base and, well, that was about it. The high learning curve was likely a turn off, and anyone who chose to plunk down their money for the single player campaign will never come back. However, once inside, you’ll never let this one go. The daunting level of customization, intense battles, team based strategy, fully realized world, and perfect controls make this the best Live game no one played.
