I realize people are very angry, and you know what? Go for it! You totally deserve to be!
The only reason why I rate relatively high is because it is MY personal experience; in my case, I had a good enough PC that after tweaking the graphic settings (such as changing the lighting/ advanced settings etc) that I got the game to work at a decent fps with relatively good looking graphics. But at the same time, I realize how pc-draining the port is, and how HORRENDOUSLY optimized the game is. Therefore, I'm not a bit upset at the angry people; whatever, they are ALLOWED to be.
Yes this review is based off my personal experience, after tweaking settings and getting it look decent. (That was the worst part of the game for me). After all this crap, I eventually started to find this to be a great game. Surprisingly so at first.
I went in expecting a horrid game, but I was pleasantly surprised (though I advise you to buy the xbox360 version to avoid the annoying port issues). The story was VERY good for a game of this genre; I dare say it even had endearing characters. By the end of the game I was relatively attached to my gangmembers; this alone was very impressive.
Another thing is SR2 was such a great sandbox game for ME personally. I hate how in GTA you have to drive long distances every time you die, when retrying a mission. I hate the tedium of losing life. I hate all the realism; it just drained on me when I played San Andreas.
the reason why I loved SR2 so much is b/c it's so stress-free. Life refills akin to Halo, police are laughably easy, and the game lets you CHECKPOINT your way through missions. That's right; no more driving 3,000 miles just to get somewhere after you die.
SR2 is made for FUN; it sacrifices realism for enjoyment, and this was what I loved most about it. Add in some awesome characters (pierce was SO funny), a great story (honestly pretty good), and some crazy side missions (like blowing stuff up with a flaming kart), and you got SR2. Just pure, stress-free, empowering fun. I also liked customizing your own gang, making your own character (been a fan of that since Oblivion), and just overall being kick-arse. In addition, I was very impressed with how my custom character moved/talked (ex: facial animations). I was confused when this 'being' started to seem unbelievably real; the great voice acting helped.
Once again, SR2 is just plain fun....uhm.. EXCEPT the porting issues. Once again, I sympathize with those that wasted money and had to deal with all that crap. I was personally lucky to have a strong computer and advanced tweaking knowledge. The average gamer, however, has every right to complain and I'm truly sorry that they dumped all that crap on you. I, personally, was just lucky to enjoy the true SR2 experience.
