doesn't that kinda sound like "reselling" or "sub-leasing" the vps which violates the terms here?
because if they was running their own personal game server that is one thing them trying to operate a post2host game server service on it is another and would cross the line of "sub-leasing" and/or reselling it then which as said would violate the terms here.

Rules are about giving the ssh access to third party.
About reselling game servers is following the providers rules and allowance.

So if you don't allow gameservers on your network please pm so I note this on the list
