UT3 makes a good LAN game. Don't think they'll ever be huge numbers online though in South Africa.
First off it was overpriced at release.
The price never decreased until the arrival of UT3Black where it dropped below R100
The problem is it was a clearance sale so those were basically the last copies of UT3 to be sold in South Africa.
Unlike COD4 which was reasonably priced and got a GOTY edition, meaning it got restocked.
So a lot of people playing it at LAN doesn't have an original copy and can't get one. The only way I know of getting a key is through steam.
I would like to play some custom maps online though. Exspecially the ne posted earlier, UT3 is missing good maps.
