Just got Leviathan Warships
based on the cool trailers. Also got the Portal
bundle, Thomas Was Alone
and Telltale's Walking Dead
. Looking at also getting the Anno 2070 DLCs, but I have to see if I can get my retail version synced with Steam first.
Edit: I was thinking about Dark Souls, but the poster above give the impression its a lazy port, so I might not bother getting it for PC and just keep an eye out at the local EB store's bargain bin for a PS3 copy.
