I bought ratchet and clank 2 when It was recently out - and when I say bought I mean I pointed at the game in the magazine and started uttering jibberish roughly amounting to "GIEF" - and it's still one of my favourite games and one of the only things from my childhood I still like. Other than that... It's not nothing, but Mass Effect. I knew it was in space, had guns, was an RPG (and yes, it is one) and had long elevators. I don't really like space games, FPSRPGs or the long loading screens, but it was £10 and I had/have many months of nothing to do, so I bought it 2 weeks ago, along with ME2. I'm now on 130 hours total play of them combined. Otherwise, I generally get a good idea of what I'm getting first.
