I think somewhere Obsidian mentioned that they were going for kind of an Empire Strikes Back theme (where the good guys didn't really "win") So that could be why they left us with the open ending.
1. It's a tie between KOTOR and TSL
2. Jedi Outcsast
3. Jedi Academy
4. Counter-Strike: Source (HL2)
5. Final Fantasy X
6 LotR: Battle for Middle Earth
7. Star Wars Battlefront
Yeah, I was wondering that too. I'm guessing the other 17 come from talking to your party members about their pasts (Kreia, Atton, HK and Mandalore in particular since they're the only ones I didn't gain full influence with my first time playing.)
