Apart from Freelancer/Disco what games are eating away your time now? I am mostly playing a heavily modded Skyrim, World of Tanks and some Fifa 15, Unreal Tournament 3, Halo on LAN with a couple of my irl friends, for now. I am thinking of trying Morrowind/Oblivion and maybe some Minecraft (curse me all you want) later on.
P.S: The other one was MMORPG specific...so why not create a more generic one :3
World of tanks
world of warships (still beta)
Counters-strike source
Day of defeat source
mechwarrriors online
Warthunder (both tanks and planes)
DayZ standalone
GTA IV
Payday 2
Sleeping dogs
minecraft (some mods)
and good old Open transport tycoon Deluxe
