Crysis vs Crysis Warhead vs Crysis 2:



1. Which has better graphics?



2. Which has better gameplay?



3. Which is more demanding?



4. Which has a better story?



5. Which is overall the best game?



Keep in mind, I am speaking primarily of the PC versions, of which Crysis 2 has a DX11 patch and High Resolution texture pack. However, all opinions are welcome.
