Even 2mbps would be on the extremely high side. I doubt many mainstream games, if any, use this kind of bandwidth. Excluding games that stream video of course.

A 6v6 game of Forged Alliance (12 players each moving hundreds of units around, many with simulated projectile weapons) uses 0.3mbps.

I was going to say this too.

Games don't need to send much data to sync game state across clients
