Well... I wouldn't normally recommend this but if you want to play UT3 knowing there's no hackers including people who mess with their ini then playing on Onlive ( http://www.onlive.com ) is probably the only place to go.  Although Onlive would be laggy if you're used to running UT3 locally with a keyboard and mouse.  The game gets ran in a datacenter and your PC just becomes a dumb terminal.  I've enjoyed playing games on Onlive but I wouldn't normally recommend UT3 especially if you can play it on the PC.

You can demo UT3 for 30 mins for an unlimited amount of times BUT to play longer you have to &quot;buy&quot; UT3 again if you can't find a way to get a free playpass. There's probably one person (THE FUTURE) on there that would give you a challenge in DM. No one on any other game type. Most people host games with bots galore and every mutator that the game includes. There's people who like playing UT3 on Onlive but, again, if you've been spoiled by UT3 on the PC then it wouldn't play as well.
