I feel you with the realism advertisements. Personally, because I played S4 League a lot when I was younger, I REALLY got into sportlike arenas, but still with FPS mechanics?
I would love to see a game like CS:GO, with futuristic sportslike arena maps, where there's like advertisements around the walls, a huge crowd at the sides like in Rocket League, commentators (maybe)? and lots of neon, haha.
