Pro Tools, for example, does this because the "programmers" who wrote it spent twice as much time on the copy protection as on the actual application.
My manpage for ptrace shows the PT_DENY_ATTACH flag. It's the second flag documented under requests...
Anyway, for what he wants to do (obviously not a commercial application), I think the mach traps are the easiest way to achieve his goals. Spawning the application into memory and dealing with an execution interpreter, as was suggested before, is IMO way overcomplicated to cheat at a game :) much easier to just beat the game...
