It uses very little data. It's only transferring positioning data and updates rather than anything else.

I was on COD4 all last night and it didn't send that much. You sure it sent 10MB in 20 mins?

My 10mb in 20mins was purely an example not an actual figure! sorry for confusion

10-20mb per hour (downloaded) for shooter or FPS titles. MMO's tend to be a bit less unless they stream content dynamically. If you start using voice comms then this is going to shoot up.

Download a netstat type program and reset it before your session then take a look afterwards

10MB per hour equates to a 55 byte packet @ 50fps.

That seems generous.

FYI - Typically there'll be an element of interpolation with packets sent at lower frequencies than actual game frame rate.

Say 10-20 position updates per player per second max, with special packets for status changes etc. Game has to interpolate anyway as packet frequency is variable (ping/bandwidth/stalls etc) 169144-ok.gif
