Ok first of all, in reference to the review that says this game doesn't run with vista, it does, all-be-it with a bit of updating from the starforce protection website. Once installed on Vista, you will get a message telling you that this is incompatible with your OS and will from there direct you to a star force link, where you can download a star force driver update. I would recommend keeping a copy of this update on disk and storing said disk with the game itself for future installs.
Just to confirm, I have 2 computers running vista home premium and both run this game. Sorry if I have caused any offence to the previous reviewer.
Ok to the game.
I have played all for available splinter cell games and this is the one I keep coming back to. The levels are varied enough to keep you interested at all times, which prevents boredom setting in (not that I have ever been bored with the splinter cell games). The targeting system has beem greatly improved and now your weapons are a lot more accurate and faster to use, very good addittion to the game.
The stealth levels in the game can vary, and the game is very flexible in terms of alarms and screw-ups during missions which is forgiving.
Graphics are excellent, even on a modest computer such as my laptop (Pentium core 2 duo 2.00 ghz, 2GB RAM and a Nvidia 8600 GS 256mb GPU.) I currently have graphics set to very high with no problems.
This is by far the best splintercell game available, Highly recommend it.
