It really depends on where the person comes from. That's why you get people who can understand FGs and can't understand RTSs, and vice versa. To ease that pain, you absolutely need good tutorials and explanations in-game, but most people nowadays bite the bullet and resort to going online as well. It's not pretty, but it's what people have to do because Capcom, SNK, and a few others don't care to put good tutorials in their games.
But eSports? You guys are seriously downplaying one of the most important things to the survival of fighting games. That shit is the only way people are going to see fighting games on a broader scale and grow as fast as it needs to. Putting it on ESPN and getting mainstream appeal? That's what all fighting games need. And then it trickles down to the players. You get them to stick around because not only are the pot bonuses bigger, but shit, now you can get sponsorship, so why not make this into a legitimate career path?
It's basically a money injection in the scene, and isn't going anywhere anytime soon. In return, Capcom, and every other developer, has to keep their product going with DLC, support, and more, because more eyes are on them. I don't think you can separate the two.
tl;dr fighting games need money to survive, both in terms of tournaments, players, and company partnerships. eSports provides that.
I think it'd be completely worth it if only to shut down that venue of complaints. The "this game is complex and it doesn't have the proper tools to teach." SFV's "tutorial" upon starting the game was a joke, as a lot of things are with the game, and it adds up. The more venues for complaints are closed, the more positive vibes a game has. And if newcomers truly aren't able to handle fighting games because of the fundamental reason that they can't handle losing, then the discussion would boil down to that instead of the actually reasonable excuses concerning what the game itself is lacking. Newcomers want to start with the resources within the game itself instead of searching for information outside of it. That process can be daunting at first.
Like, 1v1 ladder in StarCraft II is still more popular than Street Fighter V (at least, it's easier to find a match). The lack of popularity can't simply be attributed to not being able to take a loss.
Yeah, covering all the bases should be the focus. Both offline and online.
But SC2 and SFV aren't really comparable since fighting games are far more niche than the SC series will ever be.
