Huh? This is under the assumption that SF4 is the end-all-be-all of fighting games. As well, I don't feel that SF4 is accessable to beginners based on the controls... I still cant understand why things like LK,LK,LK are just frames. To me, SF4 is accessable because of the flashiness; flashiness is enough to overcome a new players troubles with the engine and controls. If you ask me, Virtua Fighter 5 (no VF game before it) is extremely accessable to beginners based on controls; it has a large buffer system and doesn't rely heavily on just-frames early on. However; it doesn't have the "flash" that other games have. Because of this, people aren't willing to give it a chance.
The most noob-friendly game I've seen so far in Soulcalibur 2. It has an extremely long buffer window AND it lets you scrub buffer (AAAAAAAAAB will be read as AAB if it exists). Its one of the reasons why so many people consider SC a "masher-friendly" series. Because any masher can play the game and make it LOOK like they know what they are doing to other mashers; when they really don't. But as I said, if you ask me, Virtua Fighter 5 is still the end-all-be-all of fighting games today. It has balance, is easily accessible to noobs with the long buffer system, and DOESN'T have a scrub buffer system. Not to mention, having a deep end game.
But... it doesn't have flash... so no one plays.
