The most LONG-LIVED Amiga games...

[Newtonian]

For me, I'd have to say:
Codemaster's Micro-Machines

I still play often to this day, sometimes against one of my buddies who's also fan of the title.

Some games for which I'll still play a game for a lenghty amount of time occasionaly:
Colonization
Dizzy's Excellent Adventures
Lotus I, II, III & Top Gear 2
Prince of Persia
BC Kid
Syndicate

- Star Control (DUH! You'd think I'd remember THAT one!)

That was a great game.

If you love Star Control, check out The Ur-Quan Masters.

It's a open source port of the 3DO version of Star Control 2 (so it has great quality music and full voice acting).  Unfortunately, the main site only offers versions for Windows, Mac and Linux (which is fine by me since I'm run only Linux on my main box).

There's a source port to Amiga OS4 done by another party:

Nobody else mentionned Micro-Machines.  Am I the only who loves that game?  It's really greate when you're playing one-on-one against someone else.

I also find the 'feeling' of the controls was perfect (like you you bounce of the bubbles in the bath level or slide in the sand level).

Has anyone else here even tried it?

I remember when friends used to visit me years ago, the game we always played was surprisingly a shareware game, it had great fast gameplay for 2 players but sometimes had problems with the way it made random maps, the game was Extreme Violence.

The game's author seems to have released it as freeware (assuming the shareware had some limitation or nag screen, I don't know).  Might give it a try.
