This will mostly be a no op. Your max MUST be at or below your real bandwidth (not interface bandwidth) and your child queues will need to reflect this accordingly. > I'm trying to limit the bufferbloat so the depth of the queue is very > important.

This will be difficult to get right with pf. Does the game always use 1500 byte packets? Ultimately you'll want a small queue limit (expect to see more dropped packets).
