I didn't actually say anything about SF4 and its quality...I was talking about MK.
Let me quote some parts of your previous post:
Go check out SF4 on PC. Game is barely alive now. Nobody "jumped on it" too. Only a whooping of 962 players recommend this game on Steam.
Ahahaha. I can't even imagine on what kind of FAIL PC MK9 is going to be. Add on top the fact that Arcade Edition was so poorly ported nothing guarantees that MK9 is not going to have such issues.
If you've meant the MK Arcade Kollection insted of SF4 Arcade Edition that's okay but I can't read your mind. Also MK AK is not a bad port, in some ways it is but the thing is that the game was quite badly put together on all the platform so it's not a PC specific issue at all.
Still does not matter. There are a lot of console port games which are based on popular engines and still are ported over so poorly that a dozen of patches are needed to get it to work properly.
Give me an example where that is the case with a game that is running on the Unreal Engine. All I can come up with is Arkham City which was not a stellar port but performed okay.
I've just checked Steam Stats. The game at the bottom of the list ATM is Batman Arkham City GOTY with 396 players online and 859 at peak. Street Fighter Arcade Edition is no where seen in that list.
The game is barely alive.
Stats don't really mean a damn thing but here are the stats for SF4 Arcade Edition: there are 3516 recommendations (Arkham City has 896) for it which is quite good (XCOM, a game that is highly successful since that day it was released has 11500 and that is a title where PC is the main platform) and there are 352 players playing right now (Arkham City has 966 players right now but the game's on sale and you can pikc up the GOTY Edition for 5 bucks so that's not too representative). The fact is that the game's doing very good if you take it to consideration that it is mainly a console title and it was relased 1 and a half year ago.
Some more stats of recent fighting games just for the sake of curiosity (BlazeBlue is not on Steam currently so I can't comment on that game):
Street Fighter X Tekken: 665 recommendations, don't know how many players currently but has to be close to zero (game was a massive failiure on all platforms)
Mortal Kombat Arcade Collection: 634 recommendations, no idea how many players currently (again it has to be pretty close to nothing)
So for SF4 Arcade Edition that means a massive success.
Yes, it is laziness. First of all, the ability to change the binds on the keyboard to suit the user should be an essential option. It will be up to the user to get used to it, but at least provide the option. Secondly, if you wanna go all competitive, and you suck with the keyboard, get a controller/game pad/whatever. This is natural. Take BF3 for example, Jet pilots with a Joystick are more accurate and can control the speed more to do sharper turns than the keyboard/mouse people. Still a lot of people do very well with keyboard and mouse given they have time to get used to it. Same would happen with fighting games, as long as we are given the options to customize the controls to our needs, getting used to it and do good is not the concern of the developer, it should be the concern of the player.
Don't voice your opinion if you're not actually playing these games. You can rebind the keys in every fighting game there is in existence on PC (yes, even in MK4 and in the MK Arcade Kollection) and you simply can't compare it to an FPS, that's just ridiculous.

No matter how you rebind your keys, you'll never be as good as players who use a controller or a fight stick because a keyboard is not fit for controlling a fighting game, period. A keyboard is designed for typing while a controller is designed for playing games, the buttons are easier to access, also controllers are almost always redesigned when a new console comes out so they are continuosly evolving and getting easier to use with every generation. I use mouse + keyboard for almost every game but there are some titles where I use a controller because no matter how skilled you are you'll just never beat people who acutally can play the game and are using more superior controls than you do.
I have never seen WB saying "nope, we don't wanna do this for PC", only seen tweets of NRS stating that.
