Yup. This happened to me quite recently though. I was bored with virtually EVERYTHING I PLAYED. COD4, MW2, COD5, NFS SHIFT, Dirt2, Dragon Aids Oranges...... The list goes on.
Couldn't figure it out at all. I'm also one of those that LOVE my oldies, I even built a PC specifically for Dos / win95/98 and 3DFX games of old, and even switched to that and could not find a single game that interested me.
I would sit there and think of a game to play, sit through a 10 minute install, only to quit and uninstall the game right after the intro :|
Since my ADSL has been off for a while (thanks to the brilliance that is Roadworks and 1x dug up cable) I decided to host a LAN, and it worked wonders
Alcohol, couple of friends, mother insults being thrown about, COD4, Left 4 Dead 2, Borderlands + DLC *cough cough*
MW2LAN was epic.
I'm still without DSL (only getting fixed tomorrow apparantly) So I decided to jog through Every single Call of Duty's campaign. COD1, CODuo, COD2, COD4, COD5, MW2 and it ain't even boring one bit
