I see too many good games for a worse SW game poll. What's so bad about TPM, TFU, EAW, TSL and TOR? I didn't even found Republic Heroes to be a bad game, although I can understand why people don't like it. They should have polished the plataforming elements.
Anyway, for me it's probably Rebel Assault or Masters of Teräs Käsi. As Guybrush Threepwood would say: Yikes.
