To be honest, apart from XCOM Enemy Within and Civ V Brave New World, everything else I want that's on Steam I can probably wait for a DRM-free release.
Hopefully Ironclad Tactics and Greed Corp make their way to the Humble Store or - even better - GOG.com eventually. I know they were in a humble bundle a while ago, not sure if they were DRM-free.
Wanna pick up Dark Souls, after realising that covenants were a large part of the game and that they're essentially locked out if you don't pay for Xbox Live Gold; but I think I might wait for news on GFWL integration coming out.
On PC you doesn't need to pay for Gold, you can play online without it :)
I know. That's why I want the PC version; I got my console version two years ago and had my fun, but I don't like not being able to use the covenants anymore, I only discovered them after the subscription ran out :D
It was an interesting day. I was either going to buy Skyrim for 360 or Dark Souls for 360; I think I made the better choice!
But as far as I know Dark Souls has some GFWL integration going on so I want to wait and see what that entails, considering the devs had some difficulties in porting to PC.
