Some games I've been playing recently over the last days/couple of weeks:
Fable 2 - really enjoyed it in the beginning but after a while it became stale and boring... not for me but an ok game nonetheless. The main story didn't go well together with the "free roaming" part in my opinion.
Gears Of War 2 - now this is more like it! Better than the first and I've just started playing it! Really nice. Seems like everything is taken up a notch from the first one... but I've heard a couple of friends of mine complaining a bit abut the ending. Hope it stays at this level though. Just awesome.
Guitar Hero 3 - This was a nice game. Only wish there had been more interesting songs. Other than that this was a load of fun. Became a bit bored with it after a while so in my opinion this is something you can't sit with for a couple of hours in a row. More like something you just put on and pick a song or two just because there's nothing else to do or if you're feeling bored.
