First off, I'd say going outside is the best option. Especially if there's a forest nearby.
But since you asked about games...
I seem to have taken a different meaning from what you said than the others did. I too feel less and less interested in games these days and find myself missing the halcyon days when there wasn't even a gaming industry. Back when games were not so much about flashy glitter and movie/tv tie-ins. That said, I'd personally reccomend some of my old favourites. (They may be hard to find, though.) "Full Throttle" is one of the best of the old-school adventure games of yore- I'd also reccomend "The Neverhood", which I have placed at the top of my "best games I've ever played" list. And since you seem to be a proponent of action and violence, "Crusader: No Remorse" and its sequel, "Crusader: No Regret" are good titles. And of course, be sure to give "Dark Forces" a run if you've not done so already. I wouldn't bother with MMORPGs, though. Those things are just cruel. You'd be much better off playing Dungeons and Dragons.
