I actually enjoy old games more than some new.
Also, I have two words: Maniac Mansion.
I love the NES game personally (because of the music), although there are PC versions. I beat the game, and it's a blast. There's some serious humor in there.
Also, the sequel, Day of the Tentacle, is also an excellent game worth trying out. It's in a more cartooney style, but it fits the game's goofy dialogue. I wholeheartedly enjoyed that whole game as well.
I've decided to not get sucked into other SCUMM games just yet, since I have enough to deal with now

Other good old games I enjoy playing are Red Alert 2 and its expansion, Yuri's Revenge. Those are very fun to play over LAN, and they work on P2s (although slowly if you have a lot of troops deployed) so you can dig out an old box and use it to play with a friend. All you need to do is install a protocol in Windows on each of the computers (Net..something... it comes with Windows, but isn't installed by default).
Also, Age of Empires II is pretty fun. I think it's better than AoE III. It's control scheme is a bit weird, but you can get used to it. Sadly, there is a limit to the amount of troops you can control at once, which is one of the weak points in the game.
Hmm.. what else... Quake 2 is one of my favorite online shooting games. It plays on just about any machine, and is still very enjoyable. Quake III is similarly good, but there's something about Quake 2 I enjoy more...
So, those are the older games I'm playing now. I'm still discovering some new ones every day. I haven't tired Civ 3, but I have that in my possession. If anyone knows any good LAN games that can run on P2s, me and my cousin would love to know (we play LAN games together between a P2 and a P4). We especially like games like Red Alert 2 and Age of Empires.
