http://www.gamefaqs.com/boards/722788-ultra-street-fighter-iv/69508985Someone had messaged me this and I thought it would be a good idea to relay it here to see what people thought. It talks about Kof's mechanics and SF's.
Some things I thought were interesting:
A lot of the people feel qualified to comment on a game they aren't familiar with, saying things like it's badly balanced based on some top 8 picks, counter pick heavy and everything else.
Obviously most people will always go with what they prefer, but people refuse to think critically.
The Kof side seems to have the debate a bit stronger in terms of how the game is designed. I'd imagine this is because the overwhelming majority of Kof players have played SF4 and other games, whereas most SF players have never played Kof.
It's interesting nonetheless. Maybe somebody wants to add an educated opinion from here. I'm just bringing it to your attention since I thought it was only fair.
