I suppose I see moments and Showdown, as challenges that require completion rather than something I enjoy doing. The thing is, that's how most video games were when I was younger. Whether it was games like Super Mario Bros, Castlevania, Metroid, Tetris, Super Tecmo Bowl, or Punch Out, they all have aspects that arent necessarily fun, but the experience of getting past the challenge was the enjoyable part of it. Those types of games had frustrating elements inherently built into them.
I guess I see the game and its modes as challenges that I get satisfaction from knowing I completed them, and because it's similar to the games i grew up playing, I dont have any issue with it.
