IMO SFV has a much MUCH greater stigma, because while I don't think it's a bad game. I do think that it's an expensive game, and the in-game fight money is SO meager that unless you play this one game nonstop, you're not making nearly enough to afford essential elements such as characters. Heck, you're lucky if you leave the latest content update with just a costume before your actual wallet gets opened.
This isn't really true. Play the brain dead easy single player stuff and play 5 minutes a week for 5000+ FM and you can afford every character, especially as each character gets you more FM. SFV is expensive because the premium, can't-earn-for-free costumes are $4. Plus, the game is always super cheap so you can get it + S1 + S2 for $40 on sale all the time so that's a lot of content and easy FM potential right there.
Firstly, almost every single problem that the game had at launch has been addressed, outside of the request for an arcade mode. In my opinion, that doesn't really matter anyway, because you can just play survival mode for an "arcade" experience and if you care about story, you'll just play the story mode. Online has been improved. Modes have been added. Online metrics are better.
I would never recommend Survival mode as a substitute for anything aside a cure for insomnia. I think SFV would be a better game if that mode was removed entirely.
I do agree with your overall sentiment. There's a pervasive negativity that surrounds SFV that doesn't accurately reflect the game. I mentioned in the OT I was expecting Evo to be pretty boring because I internalized the narrative that SFV was boring to watch and was surprised at how exciting it turned out. I also expected a ton of Laura, Rogs, and Uriens because the narrative is SFV is unbalanced and they're the top tier but none of them made it into the Top 8 which featured 9 different characters across 8 players.
The issue is people believe SFV deserves the negativity because of the terrible launch. If one thinks that a game always deserves shit, regardless of its current state, because the launch was poor then that's that. Capcom can't go back in time to fix their mistake so the impression is set.
I don't believe it's fair but it is what it is. I think it negatively impacts the game because it's treated as if it's the same game that it was last year so there isn't incentive to improve. It has the negative impact of confusing potential buyers who read outdated info or outright lies that people will spout because shitting on SFV is the safest stance one can take. Pro SFV players shit on SFV on commentary for SFV. At this point justifying one's speech as "people deserve to know so Capcom will do better" is bullshit because if they're moving in the right direction the criticism should start to yield.
Honestly, SFV being terrible is more of a meme than anything. I don't think there's a lot of truth in it and if there is, so many other current fighting games are worse in many of the same ways. Unfortunately, SF is popular enough that people have an opinion on its failings. The only game I see starting to get a lot of the same criticism is Tekken 7 which is one of the few popular fighting games out there. SFV might have terrible netcode compared to IJ2 or KI but it obliterated games like KOF or Xrd. But you won't see people raking those games over the coals because most people don't play them and they'd probably sell just as many copies if they had no online play whatsoever.
