I was playing demo on PS3 and I realy realy like it, I was so close to buy when I realize that this is Bethseda.. after Falout and goddam SKYRIM i was like F...NO to Bethseda games on PS3.
To bad my PC grafcard cant handle it, so here is my question. Is this game that buggy and unplayable like Skyrim for example? shoud i buy it or better spend some money for grafcard and play rage on PC another time?

Don't worry mate - Bethesda is only the publisher, another company made the game - "id Software". It doesn't have lag issues like Skyrim/Fallout

It does have issues though, as you can see on these forums.

well if ur only looking for a short experience then sure I completed it in 8 hours. I did couple of the boring and generic side missions but hey 8 hours to me in a rpg style fps is pretty short

Buy
