The OG Crysis (and warhead) is still one of my favourite games, don't care much for the remaster. I am glad I've got the GOG saved.
A word of warning on the original GOG downloads, the 64 bit doesn't launch unless patched (I cant remember what the exact issues was) I had to get c1-launcher-v6-build (who knows what version they are on now) to get it working.
