Yes, MK11 is a good game, and I don’t really play fighting games (normally i’d just go thru every characters and try out their flashy moves).
But MK11’s story mode is really good. The story is nothing groundbreaking, but it’s really fun and entertaining, and it shuffles the characters you play as, and that’s the strength of the recent Mortal Kombat games over other fighting games.
Also, if you want to save money on fighting games, always wait a year or two, there’s always an ultimate edition with all DLC characters in it, that’s probably selling at half price.
It doesn’t make sense for casual fighting game fans to buy fighting games day one anymore.
