Ha, I see they also remade Full Throttle!
A bit late to the party but I like talking about that stuff 
1- Without a doubt, Ultima Online.

The game is still alive but I doubt that it’s the same game I played years ago. You can always find “gray shards” that you can play different eras of the game. It seems that you can also try it for free on the official servers.
Here is a gameplay video I just found. Current version looks pretty different from this video.

They did a postmortem for the 20th anniversary this year at GDC. Definitely worth your time.

2- Ultima Online, again. This game is the sole reason that I’m a game developer now. I’m not good at pitching so I’ll just try to sum it up in one sentence. “Think about a game where the mechanics are same for everyone but every single player will tell you completely different stories.”
3- For profit but I aim to have fun while making profit

Wing Commander ][ - it was actually made in 2D using scaling and rotating of sprites to simulate 3D, so that fits right RG? Fantastic music and incredibly immersive gameplay

Crossfire, a tough and fun little game that came out for the Apple ][ and maybe C64…

- $$$… its a really hard business these days - fun and painful…
