I guess this only makes sense in the context of consoles, but I think it would be cool if there were some game where every move was made up of combination of buttons pressed consecutively Like if walking just wasn’t as easy as moving a directional pad but required some complexity
play Magicka if you haven't already
walking around is basically the only thing that isn't a button combo
also I'd argue that some genres like fighting games are so fast-paced and intricate that playing them at all is one big button combo
