Morrowind was great, except for the combat. I only played through it because I had fun exploring! That's why I played <img src="/ubbthreads/images/graemlins/div.gif" alt="" />, too.
TOEE was amazingly boring, so I barely played any of that.
Lionheart... sigh. Well, even after the terrible demo, I bought it first day and played some of it until my hard drive failed and I had to format. Never reinstalled it, never will. I guess I only bought it because I respect Black Isle. Or respected, I guess. RIP.
I guess my favorite types of rpgs were Infinity engine games other than Lionheart. Icewind Dale 1+2 were spectacular and Planescape: Torment is still my all-time favorite game in every aspect imaginable.
