Yeah, of course, if the max transfer rate is 3.0kB per sec, of course
the data
sent in this time has to be less than 3.0kB

But if've heard of other commercial games having big problems with
mutiplayer
playing, not because the data transferred is to large but simply to the
ping delay between client->server->client

I've never played that online, but XwA/XvT should have some instruments
there
showing you your pingtime, and when it goes red, the delay gets too
long.

Are there fast commercial games playable per modem? Really playable on
internet
servers some distance away? I think a german magazine said "...Well..."


Correct me.

For my game, I'll do first concentrace on running it on 10Mbit lan.
This may sound wrong too you, but it will show success (hopefully) quick
and
then I'll think about improvements etc.
