Moo 1 is just awesome. I couldn't stand 2. All they needed to do was make 1 with multiplayer. Change nothing else and it would have been great.
As for old school SSI. I think I have champions of krynn and secret of the silver blades for my commodore somewhere.
I have the FR Archives as well. I never got a chance to go through them all. But I had when I was much younger.
Full throttle is another not so old adventure game that had a lot of spirit. I think it was 1994ish.
