The good.
Some graphics are better

The bad.
Graphics only load sometimes.
Sounds are a straight downgrade, They are buggy and random.
AI on (Hardest) Post human difficulty is either lobotomized or John wick with x-ray vision.
Multiplayer is removed (too be expected).
Animations ingame are even worse than HL2 from 20 years ago.
The game is very unstable, Doesn't matter on PC/Console the AI will throttle the CPU.
Also crashes, I got 5 some people got more, what's your high score?
Still uses the Crysis 2 plot and plot holes, Was never a fan of it, and nothing was changed/fixed.

Just buy the original if you must play Crysis 2. I should not have.

A great remake for a great trilogy. Only reason I can't get past 5 hours is because I go back and forth between playing from my desktop and laptop (laptop is often most convenient) and I get sick of having to carry my game saves on a memory card from one PC to another. In fact? I was wanting to play tonight but I left my memory card at work. More often than not? I'd rather just not deal with it and can't stand the thought of having to reply a bunch of stuff I just played the previous night, when on my desktop. I had no idea a game could release without supporting Steam syncing. First game I've owned like it.

One word. Masterpiece.
