I started playing in a semi-regular one at around 1993, it was a spin off from the events of another one which was running for a year or 2 before that.
Over the years some of us moved away, namely me, so its 3hrs travel each week to get there and back, but being a fuel injected suicide machine with a fast car means its an excuse to drive. So its on and off when we can throw together the time to catch up with each other.
2E, while it had its good points crippled the game at around 21'st level to the point where we decided to give it a rest for a year or 3 and played shadowrun, vampire and SLA industries which didnt have levels and didnt get borked regardless of how long they ran for.
Then 3E came along, and being the jaded, irritable prick I am I didnt really feel like playing another run of D&D (which I in some elitist opinion, I must admit, felt it was kiddy role playing and still do to some extent) so I stopped playing for a bit and wrote game supplements and fiction for SLA, and played that and whatever else 'but' D&D.
Such was my bitterness from 2E.
Well, we ended up playing 3E and dragging out the old characters again for another run, I was dubious and not without good reason, new system, stupid rules for 2E-3E conversion written by bastard maniacs and it took me a few months to get used to the new game and un-gimp my former fighter-wiz, which was carried for awhile until I found my feet by the rest of my friends.
(Though, if I ever find the person responsible for 3E multiclassing, god help you...)
Anyway, we've run the oldies up to 32nd level and taking a break for awhile until we can figure out how to house-rule and un-bork D20 to make it work. So instead theres a 2nd game with a different DM of goodly low level gimps running around in Greyhawk that the high levels changed greatly.
Also as side project there is a game set in the same era post high levels where the party is an unholy pack of evil scumbags and Im enjoying it immensly, though I have been told by the GM that perhaps Im enjoying it too much and if he finishes his psych degree will be able to determine just what my major malfunction is.
Actually, I can tell him that now

Hygric, Im and evil and horrible man... muhahahah!
So, if its not my 32nd fighter wiz. Then Im playing a 6th level LG Ice barbarian fighter rasied by dwarves, or on the really naughty nights its a 7th level Succubus/Incubus defiling innocents and making other PC's dry-heave... but the game goes on!
3E is a very fun game from L1 to 20.
After 20, well if your willing to try/cry very hard and often then it can be worthwhile too.
