I've played UT'99 for nearly 10 years semi-competitively in Europe, and played a littlebit of UT3 too.
Anyway, currently I'm only playing QuakeLive as online game. They have official servers in Singapore. The game is free and it will download itself, because the website is the interface, but the game runs in a special OpenGL object. QuakeLive has a sizeable pro scene, and you can watch numerous matches and tournaments on Youtube and twitch.tv. The quality and skill of these pro gamers is unmatched in any scene, except for StarCraft2 perhaps.
UT has almost no future, Epic Games will probably not release a new UT, and they don't do much to improve the existing games.
Therefore I would like to see more Bangladeshi UT players start playing QL, because currently the servers are dominated by others... And because QL is relatively close to UT in terms of gameplay. Still QL is extremely difficult and you will need to punish yourself hard to master it, like a real gladiator.
My account is TNZ @ QuakeLive, you can invite me as friend, but I can probably not play you, because I'm on higher skill-tiers after a lot of practice.
