1: Sandbox 3 - Crysis featured a big modding community, and those who wanted to wait for Crysis 2 and sandbox 3 are disappointed. The have plans to release a UDK version of the Cryengine 3, but i still would like to see a Sandbox available trough a patch of standalone download for Crysis 2.
2: Include more graphical options - Let us change Texture detail / Motion blur / Shaders like they did with Crysis & Warhead.
3: Include a CPU & GPU benchmarking tool, wish was included with Crysis. When Crysis was released everyone wanted to show of there rig, telling that they where able to play Crysis.
Have more stuff you where expecting for Crysis 2 but didn't include, Post it, and a good reason why.
No HATE Comment!, those will be deleted.
Good luck,
