if you'd like to have a guaranteed bandwidth for that games, use a smart router and prioritize packets of the games. mikrotik routerboards such as RB750 series are dirt cheap and will do the job just fine, provided that you can configure mikrotik's routerOS
if its like ISP's in australia, they cap your upload as well. some ISP's here shape you to 128/128Kb, others 128/1Mb, and others even more random combinations.
the only reason he should have issues is if he runs out of bandwidth, and that would be because of other users or programs on the network - someone downloading or uploading, would have a greater ping impact with lower overall bandwidth.
