Well Crytek is already very good at making Cry puns themselves

And using crysis isn't really a pun now is it? You couldn't pronounce them since you replaced crisis with crysis. Try this:
Random person: Crytek, crynet systems, crysis, cry engine! Too much cry! Stop it!
Crytek staff: Go
cry me a river.
Random person: Aaaaaaarrgh!
