Even if you had ut2k3 it was still worth buying unreal championship because of the default gameplay was different plus it had more than just two exclusive maps like that crap direct pc port unreal tournament 3 on 360.

stock default gameplay mode  in ut2k3 and uc1 is night and day difference.

The games really did play alot different ut2k3 was alot more grounded and uc1 was more aerial.

Look at the jumping height  in unreal championship 1

Then

look at the jumping height in unreal tournament 2003

(Even with the quadjump mutator which makes it no longer standard default gameplay in ut2k3 you still dont jump as high as uc1 lol i done tests.)

unreal tournament 3 on pc and xbox360 and ps3 have the  exact same weapon models that's not true for unreal championship 1 the rocket launcher is completely different from unreal tournament 2003.

Also the people did not jump as high or take as much damage in the pc version.

unreal tournament 3 on xbox360 is a direct port of the pc version it has like two exclusive maps the gameplays the same though.

unreal championship is not a direct port of ut2k3.

original xbox actually had two quality fps exclusive games halo and unreal championship even part 1 plays completely different from the pc and it has exclusive maps.

Xbox is practically only made for people who dont play pc fps games and love halo now and the multiplats fps they cant play on their computer.

PORTBOX360 HAS BECOME A REALITY LOL.

Xbox is no longer allowed to appeal to pc fps fans who dont like halo.
