I think for now, I'm more interested in MKX just cos I haven't played MK games for forever so this one seems refreshing to me, and the characters are starting to appeal to me. I like the idea of being able to play as 'god' characters like Raiden, but I love being able to play as superhumans like Raven or MMH (I love MMH but I know ppl hated him in Injustice so I didn't want to feel cheap and use him a lot lol, but when it comes to top tiers, that's a whole other conversation!).
I definitely feel like I want to get attached to characters in order to like them. I'm not saying I'd play a crappy game just cos it had DC characters in it lol, but a game could have really good play mechanics, yet I won't necessarily care about giving it a try. Hopefully this analogy works, but some movies might be considered good despite having no characters to care about, such as that movie 'No Country for Old Men', which I think won the Oscar for best movie of the year at the time, but I heard all the characters were pricks, so I didn't care about them surviving throughout the whole movie, and never saw it lols.
Maybe I'm just closed-minded but even for fighting games, I like a wee bit of character background to make me them seem interesting and make me care about the characters. I guess that's why I like the idea of comics (I don't really read them but I like the idea of games based on comic characters). I'm not saying I have to be able to relate to them, but it's easier to get my attention with a game based on Bats or Supes than a game with generic-looking ninjas in differently-colored costumes, though I know MK characters look a lot different now, since the days of the first few MK games lol.
I guess I'm a kid at heart, but I often like to imagine that I'm playing a role in a comic or movie, etc. while playing even a fighting game. The more I read about the fantasy world of MKX and its predecessors, however, the more it seems like a comic and the more I want to play it: cheesy or not. I guess I want escapism lol.
I'm not sure which game I prefer in terms of mechanics, though. I liked a lot of the features of IJ such as interactables to an extent, the clash system for variety's sake and less predictable match outcomes, and traits, and ALL the super powers
, and I overall do prefer back to block over a button so I can move back and forth while blocking (though the block button helps against ambiguous cross-ups, which maybe should bother me more than it did), and I wish combo breakers in MKX used less bar, but maybe I'll change my mind about that, but I LOVE the variation system for MKX. I just hope the game doesn't come to counter-picking all the time, which might be a prob in most fighters (I mostly played SF3 years back, and that game was simply about the top tiers dominating instead of counter-picking, so pick your poison and good luck finding a balanced game...).
