I don't think they're that great. The engine is great, certainly, but crytek as a game company not so much. They were at their best when Crysis 1 was made, where you could have your own servers and mod things and communities were built. But the second they could get into the Call of Duty userbase, they actually deleted all their mod forums, which included hundreds of thousands of posts and thousands of mods and configs for servers. All to 'make room' for Crysis 2 'modding', which was non-existant because you could not own your own servers, and server sizes were tiny.
