Hey, how about that Bayan DSL thing with the old lady screaming "flashbang! flashbang!" is that good?
Internet gaming depends on the server (location in the world) you are connecting to.
In general, 3G based internet is bad for gaming because of high latency.
Based on my experience, with a wired broadband connection, I can only play FPS games based around the general southeast asia region. Beyond that, latency becomes too great.
So that limits me to playing on servers based in Singapore, China, Hong Kong and similar. I have tried connecting to Australian servers but latency is borderline bad.
