There's no activation limit on the original Crysis. Only Warhead has an activation limit and there's a de-authorisation tool available so that you don't have to use any up, so long as you de-authorise the game before reinstalling it

How strange then that my original crysis bought on steam tells me i cant play the game, all i get is the message to buy a new one, warhead still works.
I change computers often so apparantly after 5 changes crysis stopped working.
When its bought through steam there really should not be limits.
Will i buy future crytek releases? NO i wont.
