- Unreal tournament 3*

*this is doubtful since unreal has so many issues with PS3. Almost all unreal engine based games have issues on PS3. IS unreal Tournament 3 not based on Unreal 3?

No it's not, the game was a ps3/pc timed exclusive. The 360 was barely even started when they released the PS3 version.
