Just an idea...

When im in singleplayer, once im done stealth killing everyone in the village, I like to dike around with vehicles, explosions, physics, whatever. But sometimes i'll accidentally die because I forgot to hit F5 for a quick save. So I think there should be an option to have the game save ever minute or so (you can change this time).

And it will help alot of the BS deaths related to physics glitches (like touching a table)

That a nice idea but no more.Autosaving make PC run slowly...,And it's excess for crysis 2...

I like games that have a auto-saving checkpoint system, but also allow you to save anywhere like Bioshock and Half-life

yeah true that would be awesome. Well there were autosaving points in Crysis 1 but these were not that frequent and besides they got stored like any other save.
They should have a 'continue campaign' option

Crysis had save checkpoints. That wasn't much of a problem for me.

I'd like the option to save anywhere. It makes more sense if you've come along way and then you have to do something else.

Crysis already had automatic saving...or you could do a quick save if you wanted to...
