I still just see it as a 60$ game people buy for the 400$+ system the own. Not a 60$game people buy a 400$+ console to play.
I will definitely buy a PS4 (or gaming PC) solely for SFV and I think there are PLENTY of people who will do the same. I don't look at my Xbox360 as a video game console. To me, it's a "USF4 and Netflix machine".
I can't play with a stick.
Yes you can.
I thought I would never be good with a stick and I tried to fight it. I bought one in July and I was GOD AWFUL for 2 months. I had such a frustration built up...it was like my brain and nervous system were fighting against my hands and fingers. But after a lot of training and failures, it's become second nature. Now, using a regular controller to play a fighting game is like using an old school push mower to mow your lawn.
I can't recommend an arcade stick enough. Not only would you eventually be better at fighting games overall, but I think it's more fun. There is a reason why nearly every high-level player uses a stick. The only ones I can think of who use a controller off the top of my head are BrolyLegs (because he's handicapped) and Snakeeyez (because he mains Zangief and he doesn't want his opponent to hear him mashing out SPD's)
