They feel the same and tbh they mostly are, fighting games as a genre haven't really innovated a lot like the RPG and FPS games have over the years, at the end of the day you still have combos, ultra combos and finishing moves, maybe some slight new scenery changes like in Injustice but that's really all there is with the genre.
I play maybe one fighter every few years, last fighting game I played was Smash last Dec and years before that it was Street Fighter IV (back before it was milked to oblivion), I really don't play Fighting games often because they feel reptitive and haven't changed all that much, I also dislike remembering combos and there being oodles of them, long string moves that you have to tap in with super precision and timing and then when you play against other people or friends you get the one person who spams the good move or spams because they don't know/can't execute combos well due to the way the game made them.
That said I find a lot of fighting games pretty to look at like MK or Street Fighter or KoF and GG/BB but I'll never be into them as I would be for RTS/RPG/FPS.
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
