I loved Crystalis, Bucky O'Hare, One Must Fall 2097, and The Phantom Menace game. Although I loathed the gungan city level in Phantom Menace. I remember there was this one platforming section where Obi-wan had to jump over these platforms that moved up and down for some reason and for some reason I just couldn't get it for ages. I have fond memories of the rest of the game though. My friend and I to this day joke about thinking that Barbo, a random alien from the Mos Espa level, is the most compelling character in the Star Wars canon. Barbo is going as fast as he can!
Some games for me are...
Dragon Force for Sega Saturn. Strategy RPG that no one I knew played... very possibly because nobody I knew had a Sega Saturn. One of the few games that I replayed over and over. I beat it at least once with every character and then some. My favorite was the samurai guy because his troops effed up dragon troops.
Vanguard Bandits for PS1. Another strategy RPG... I really like strategy RPGs. This one was more in the Shining Force/Final Fantasy Tactics vein, except you were fighting in mechs. It had multiple paths and endings and was awesome.
