You haven't played New Vegas yet ? Slacking mate!
Played a little bit of Fallout 3 back in March 2010, and didn't take to it. I only got 40 gamerscore. If memory serves I was in a bunker, made it outside, and got no further - wasn't enjoying it.
To be fair, I probably didn't give it enough of a try. Was the only Fallout game I've played, so I was in no rush to buy New Vegas. Decided to stick it in my steam backlog when I saw it going for a quid or two, though.
Was similar with Elder Scrolls. I didn't take to Oblivion at all - but perhaps didn't give it enough of a try. Bought Skyrim when I saw it cheap, and ended up playing it for months - was one of my favourite games of the last generation.
Currently replaying the Arkham games, ahead of the new one coming out in a couple of weeks' time. I've done Asylum, and am about a quarter of the way though City. (I won't bother with Origins. Ironic, really, as I've already played Asylum and City on the 360, but have only played about 10% of Origins. But it's not Rocksteady, and just didn't seem all that good.)
Bought "Trivial Pursuit Live" on the One yesterday - reduced from £12 to £6. So another for the backlog. Maybe a waste of money, given I've not played on the console in over three months, but I've got about fifty quid xbox credit on my account, and one of the kids mentioned a month or two back that she's never played Trivial Pursuit but would like to, so what the hey...
