Well, this is a little off what this forum is about but hey, I feel you gujys are up to the job.
Does anyone know if there is a playable demo of Crysis?
If so so please post a link.
Even if a playable Demo is planned, I doubt it's available yet:
...A next-generation project by CryTek, makers of the dazzling FPS Far Cry. This game is running on the new CryENGINE 2 technology. The game is one of the the first announced to run on the advanced DirectX 10 architecture.
I don't think a Demo would be released before many prospective customers actually have DirectX 10.
The quote above is from here.
