Having bought SFV knowing what I was getting I'm still glad to see Capcom getting slammed. The release is a mess far beyond the usual launch shenanigans, pick a random mid-tier early access title and chances are it'll look as polished as a classic Blizzard release compared to SFV. Also praise Sony for granting us the gift of a sequel to the most successful fighting game IP in the world that would not have been possible without their generous funding and world-class development help.
After playing it for a bit, I feel like most of the press reviews have nailed it. To paraphrase:
"If you want to play seriously online or 1-vs-1 offline, or start practicing to do so against other random people online, you could consider picking the game up now. The servers are currently destroyed, but that'll probably be fixed in a day or so.
If you want to mess around with more than 1 of your friends in a lobby online, or play just about anything against the computer, a real training or challenge mode, or anything offline other than human 1-vs-1, you should absolutely wait."
It's clear they hilariously rushed the release for the pro season. Basically, unless you want to dive directly into competition against other randos online, hold off on purchasing.
