Honestly, I think its just that people are getting upset that others are putting unrealistic expectations on the game and then are having a frenzy posting threads in this part of the forum that the game doesnt live up to them. People arent defending a multi billion dollar corperations, theyre defending reality. Rockstar cant possibly add every feature that every person wants, there has to be some kind of comprimise. People arent getting upset because some people dont like the game, they get upset because some people are complaining about trivial things that they would have done differently, not actual faults in the game itself.
I personally enjoyed the game, ive played it through twice and enjoyed both play throughs. I personally dont like the vehicle handling in the game and think that IV was superior. But I dont post up 3 threads every 30 minutes crying about it, because it is just my preference and not an actual fault in the game, I can see the sense in why the simplified the handling.
Dont act like R* stole your money here, they didnt force you to buy it on release date before the user reviews were written. Some people really just need to grow up.
I too prefer IV's driving, and by a large margin. I also never felt the urge to make a new thread everyday about it.
OP, its got nothing to do with opinions not 'being allowed'. If people were coming through and dropping their 2 cents so be it. But there are people harping, and repeating themselves over and over. It gets old and does nothing to improve the game.
Endlessly repeating requests is what children do, in the hopes that the answer to the question will change (usually from no, to yes).
