Only considering the games that I have bought for all of my consoles.................
I probably have enough titles on my shelves to last me another 5 years or so.
Plenty more games are available that I haven't purchased yet.
I could probably easily stay busy with the consoles I have for another 10 years.
Hell, I still have games for the original Xbox that I haven't played yet.
Once a few really good exclusive titles hit the shelves then I will start deciding if/when I want to break down and buy another console.
I would much rather go to my grave not needing my gun, than go there wishing I had it.
