It all depends on the gameplay, features, rules, layout, art, call outs, etc... Theme is a just a part of the mix really.
The theme doesn’t really make or break a game for me. It certainly can make a game more or less desirable, but there are a lot of other factors in a good or bad game.
Avengers = great theme, don’t like the game
Metallica = not a great theme for me, love the game
Dialed In = weird theme, love the game
Star Wars = love the theme, don’t like the game
