See now that's the thing, VF in general is not a popular game as a whole because the series just doesn't draw in the appeal out there (Before it did, but now not so much due to companies stepping up in the graphics department and more team members in the genre.) Game doesn't have a proper story mode, barely any American commericals, graphics with an outdated engine. VF stays alive because the community is out there trying to support it by tournaments, streaming it, local JPN arcades (Big one), retweets to SEGA etc. However, this alone is not the huge issue but rather SEGA's issue on money problems. Issues with the Dreamcast in the past and the switch to mobile gaming (Not a hard switch but rather a focus to it. It does not mean they will only make mobile games. They will still make console games.) Shenmue III's kickstarter made more than the goal and likely part of that money will be used for bonuses on Shenmue III.
If anything, they can even provide the thanks with a likely attempt to provide a demo digital code for a VF6 in Shenmue's III purchase. (The chances of this happening is slim since it's not even confirmed if they been started working on VF6.)
If a move is a fast, safe and does alot of damage then changing the input isn't going to do didly squat." - Yes it does. You are forcing players to react to certain moves that potentially can do more damage than a natural combo. You are having players have easy access to make their life easier. None of that easy crap will ever be in there, thank god.
"you can put an execution wall as big as china behind if you thinj thats going to stop people from abusing it." - They can and they will. If it helps them to win, they will use it without question because now the attempt is easier and the brain does not process to always avoid it.
"Go see how well that worked for Street Fighter IV when they changed the the mechanic for cancelling normals into specials." - And then they added other logical ideas to it so that things do not get easy.
^Loool! Just read the rest and I forgot I am dealing with an individual who clearly believes he has an understanding to the meta and process for how a game should work.
