I would say execution, which most games do a fine job in dealing with.
The problem is that on this day and age, is no longer about that barrier of entry, but the fact that since you have online play and constant online presence, most people feel that they are not playing the game if they are not playing/doing stuff seen at high level, combine that with the predominant entitle mentality many have that they have to be catered and that there are multiple games fighting for your attentionj, then we have a problem that is not only about barrier of entry, but how rewarding is your game for you when playing online.
It is why you see people bemoaning when a game requires you to learn it to be able to do decent online.
Since before 2009 we have a lot of people saying that motions for specials are an unnecesary barrier of entry for example
I think that most games do fine with their barrier of entry.
Is just that FGS like other niche games lack the appeal of instant gratification that other games offer, like Overwatch for example.
FGS over the years have been trying to do a lot of stuff to increase the accesibility, but they playerbase hasnt really grown over the years.
So is not really a matter of how accessible they are, imo.
There’s no way execution could be something at this stage. The only people complaining about execution at entry level are Fortniters hyped up on G Fuel, and these are the same kids who build the Great Wall of Mexico in 5 seconds in a gunfight.
I think SF3’s Makoto’s higher health and frankly ludicrous dash was something else. People complain about 15f Dashes now. Makoto had a far reaching 11F forward dash and 12F Back Dash. That’s just plain nuts. SFIV Makoto had much slower dashes (16F and 27F) and below average health. Plus in SF3 Makoto could juggle you into oblivion.
It may also depend on the matchup and skill gap. SA1 is more threatening at all ranges than SA2 which requires one side of the screen. It also deals damage more consistently, and is just as easily confirmed into. It’s scary stuff.
