Okay, we know that most everyone is still playing Grand Theft Auto IV. That's fine. We can accept that. However, with summer fast approaching, we find ourselves reflecting on games past. Given the usually thin trickle of releases during the summer months, it's a good time to take some older (and cheaper) games for a spin. For instance, we just wrapped up the single-player campaign in Marathon: Durandal for XBLA. The upcoming DLC got us all excited, what can we say? Of course, we don't speak for everyone, so we must ask again: what will you be playing this weekend?
