Dang, wouldn't you run into serious internet problems with that? Do modern games use that much data? Could a single internet service handle 6 simultaneous connections?
Really is not that much data involved (not counting downloading the game itself). Streaming multi-player game data to/from an individual player can range from like 10kbps to 100kbps depending on the game and scale involved. Remember you are only sending the deltas (and occasional entire refreshes).
Latency is a lot more important than throughput for online games
Absolutely - especially when we are talking about first person shooters.
