Having never played KOTOR or KOTOR2, I can't include those... Here's my list anyway;
1. Star Wars Battlefront
2. Star Wars Battlefront II
3. Star Wars: The Force Unleashed (PSP, PS3)
4. Star Wars Battlefront: Renegade Squadron
?. Hopefully Star Wars Battlefront: Elite Squadron
Yes, I love Battlefront. Give me SWBF III!!!!!!
