If you have a system that can run it, Crysis will instantly become your favorite FPS. Brilliant work!
Gameplay: 10/10 -- highly developed gameplay that leaves many choices to the player. Weapons feel amazingly good and authentic. Movement and the AI is one of the best seen. You can immediately see that lots of time, work and imagination went into developing this game and it shows. If you can actually play this game (due to its enormously high system requirements), you'll enjoy every second of it.
Graphics: 9.5/10 -- almost perfect graphics ... maybe even perfect if I could enable anti-aliasing. My very subjective view is that the HDR is still lacking the simple beauty of old and battle-tested anti-aliasing (as also seen in Far Cry and 100s of other games). Maybe this looks better on a crappy Vista OS with its DX10, but that could require tons of additional memory to handle this game.
Sound: 10/10 -- great ambient and battle/weapons sounds that greatly enhances the gameplay.
Value: 10/10 -- even today I still play Far Cry and I see that happening with Crysis too. You simply never get tired of Crytek's creations. With modding enabled this will be a great added value and almost an endless replayability of this game.
Overall: 10/10 -- technically this is the best FPS game of 2007. Other top 2007 FPS games (R6 Vegas, STALKER, CoD4, games in the Orange Box) may overshadow Crysis in a short run since they run smoother on mid to high end range of current computers. Maybe upcoming video cards drivers or a game patch will improve Crysis performance, but regardless, Crysis is a great achievement and people will still play this game quite a few years from now. And, of course, a great praise for being a genuine PC game rather than a console-to-PC "handout", which is sadly a rare occurrence nowadays (STALKER: SHOC comes to mind as another genuine PC project). Anywho ... a must have game!
