The games are based on the CryEngine 2, is thus:
1. The graph absolutely top (ATI HD 5770 - 1920x1080, 4xAA, Settings: all on high -> runs perfectly and liquid).
2. The physics very realistic - with grenades and rocket launchers can disassemble everything, even thin trees can be cut down with weapons.
3. The Games are both DirectX 9 and DirectX 10 capable.
4. The games are available in the standard 32-bit version, as well as a version for 64bit, which brings a small speed advantage.
5. The enemies are very clever and not make illogical actions, as is often seen in games.
6. The animations and sound are very good.
The cutscenes are well done, the story is a shooter also very good. The gameplay "Power Struggle" in multiplayer mode is super awesome and the Crysis Editor - CryEngine 2 Sandbox - is part of it, so can own professional Crysis worlds create. (The Crysis maps can view).
Also the Crysis Dedicated Server is part of it, can be created with which own Crysis server.
"What is the EA Classics version the poor?" Who asks himself:
No, it is the same version as the Crysis Maximum Edition, only in an ugly cover and only 20;)
