SC1: A solid game. Good music when needed. The game guides you well, and lets you know about potential risks ahead of time. I liked the story.
SC2: So far, a pretty crappy game. Controls are less reliable (he wont grab ledges when he should have), music is often just an annoyance, the mouse is laggy, the sound has had some popping issues, the nightvisions runs in a terrible low resolution mode, the story just isn't that interesting and isn't put together well. I could be on the last mission for all I know. The game really doesn't give you any indication of the importance of your current role. There is also WAY too much trial and error, rather than real strategy.
SC3: Seems like it could be the best of the bunch. Looks fantastic. Runs fantastic. Really pushes my hardware well. I can't find any bug, glitches, or gameplay quirks. A solid PC port. The new moves are very usuable. The AI seems improved. The music seems more appropriate, just like SC1.
SC4: Insanely buggy. Everyone on the UbiSoft forums are going nuts. It's nearly unplayable. The menus take forever to navigate. Load times are terrible. Performance is terrible, despite the game actually looking no better than SC3. The game takes up over 10GB, whereas SC3OK 3.7GB. The game randomly crashes, and no one can find a fix. Even running on the lowest settings doesn't seem to help. If they are able to patch this game into a solid state, then it might become a great title. The story has a lot of potential, right from the very first mission. I can't say much more unless Ubi fixes this crap.
