Only thing I found that was fun in the first one (or rather, the expansion to the first one) was 'Crysis Wars'. Not really because of the online, or that it was fantastic... It was just that you could bring the CD to a friend's place or wherever and install on as many computers as you liked, without any hacks or whatnot to get it working on LAN. I miss this in modern games, I really do.

As far as I know, in Crysis 2 - this doesn't exist.
Code:
assert(fun > 0)
I got a false assertion.

(Also, for the unlikely few who care - I'm still around [Oh no!] - Just ghosting, though.)
