Just got my PS4 copy today. No trouble finding matches and only minimal intermittent lag. Nothing brutal yet.
Tried some casual SSF2T first, won all my matches handily with Honda, so I tried ranked for a bit and I won about 80% of the time. Only one guy really messed me up with Dee Jay. He just kept crossing me up and I had no answer. Other than that, I was surprised at how good I did considering I hadn't touched the game in a good 8-9 years. Pretty much felt like I never left.
Then I tried 3rd Strike, which I also used to be pretty good at. Did not fare nearly as well. A few guys schooled me pretty hard, even in casuals. I've clearly forgotten how to play this game well.
Also my thumb started to hurt after a while, which gave me memories of when I'd play HD Remix for hours and hours when that came out, but that was after several days of heavy play in a row. Now it's happening to me after a few hours. Getting old sucks.
