Well known online poker games are about as far from abandonware as possible (with millions of players around the world logging into various sites every year to play Texas Holdem games), but they're still a fun way to pass the time.

While you won't get rich playing Frogger or other PC games, you could very well strike gold with online poker. Top players can make well over $100,000/year playing poker, so if you play your cards right you might have the best of both worlds, having fun and making a ton of money!
