Borderlands is amazing in single player, but I would not mind someone joining me now and again, but I guess most people have moved on from it now.
As for Dragon Age, it looks good, but there are some low review scores here and there.
I would love to get Demon Souls, but for me its a 50/50 game and I am not sure if I would enjoy it, especially the apparent difficulty level and refuse to pay £60 on ebay for it. I do hope it gets a UK release soon.
strawberry float what the critics say, Dragon age is amazing, it's submursive and amazingly well written, most of the review scores have been based to graphical errors, it's a bioware game these errors come 2 a penny! But enough said, it truely is a fantastic game, if you are unsure about the actual gameplay youtube some vids of it.
