Yeah, a new VF would be awesome. For now, I am content with Tekken 8 and MvC2 until the new Fatal Fury game comes out. I may try out Elena or Mai in SF6, too, see how I jive with them. Pocket Bravery is an indie FG I'd like to play more single player content for to get unlocks and such.
MK was the only 2D FG I played for basically all my life until 2017 when I dived into air dashers. I have been tempted to re-install MK1 just to occasionally check the cosmetics store. I heard they were giving out free skins on a rotational basis for some time recently. But damn, it's a huge install, like you said.
I still love MK, I still play the story modes, watch the movies, watch tournaments, get MK memorabilia, etc. I just can't get re-acclimated to the gameplay anymore, after playing more and more other 2D fighters in recent years.
As a sad side note story, Guilty Gear used to be my #1 played game and probably like 1A or 1B as my favorite FG franchise, along w/ MK. I then got banned from ASWU's twitch chat because I typed out a middle finger in text emoticon style (which is just ..l..) and the automod permabanned me, I think confusing it for a penis. Or maybe they don't like middle fingers either. Regardless, it seemed extremely petty for a one-time offense permaban. I appealed, even talked to a CS rep twice and they would not lift the ban. So...I decided to no longer support ASW.
I really do miss Guilty Gear. I would love to play Strive again, and UNI2 (which I know isn't an ASW-dev'd game, but they do publish it, so they'd get money from it). Oh well, MvC2 has been a real savior, as busted as it is lol.
