okay first of all I think Griffin is stupid to think a game like Metal Gear Solid 4 didn't improve on the controls from the previous games. Ofcourse the controls were fixed. For the record, the controls are completely different. They are now more like american shooter games. You even have the option to play first person the whole game if you want to.(although I don't recommend it because it makes it a lot harder to be stealthy, which is the whole point of the game.)
Now back to the original question, there are multiple reasons. Some people just don't care because there ignorant. My friend wouldn't buy Metal Gear Solid 4 but when I told him to preorder resistance 2 he did it in a second. He had never heard of metal gear solid before. This is because there marketing campaign sucked. Another friend I showed it to hated all the cutscenes. Another friend I showed it to just sucked really really badly at the game, so bad, I told him it wasn't worth getting it. Metal Gear Solid games are among the hardest shooters. It took me a few trys just to get past the first level of the original Metal Gear Solid.
