You clearly have no idea what you're talking about. Anyone can mash out special moves but the spacing of the combo hits is much, MUCH tighter, meaning your execution has to be 100% to land 1 frame links. 1 frame link = 1/60th of a second, meaning you have to time your button press to coincide with a specific frame inside the 60frames per second that the game runs at. Try landing that consistently along with perfecting FADC's and option selects and you'll see that SF4 is a far more difficult, much more in depth and far more technically demanding game than the latest MK. Also, the combo's are NOT the same. Hows that for clever?
P.S I'm not saying MK is easy, I'm just saying SF4 is much harder.
Depends on your definition of worthwhile. PC owners are hardly elitist just because we won't buy every POS game thrown to us with overpriced DLC attached to it like the vast majority of console owners. That's the kind of nonsense that has us in the sad state of affairs we currently find ourselves in. We expect more for our money, and so should console owners.
Your comment is like saying why go to a fancy restaurant when you can eat junk food and feel just as full. Because it's the experience that's the most important thing not the end result.
