Unreal engine I think.
And Planet Moon made A&D, which could have been a lot better if they weren't rushed to get it out the door. LucasArts used to consistantly
make great inhouse games. Ones that weren't even SW related, mind you.
Then not so much.
Republic Commando looks to be great. Perhaps they're coming out of the slump they were in. Now if only they'd also get back into games like Grim Fandango and Sam & Max.
EDIT: And Monkey Island. I'm sorry for forgetting. Don't hit me.
