My last build revolved around categories. It has dedicated buttons to navigate them.
I've found that if I'm in the mood for a particular genre, I'm more likely to try something new if they're divided into categories.
If I have to browse through a list of 2,000 games to find something in the genre I want to play, I'm probably just going to search for something I already know.
This machine is all arcade games, no consoles. I do have a separate menu for PC games and Steam.



The Beat 'em Up genre includes Hack 'n Slash games as they are basically Beat 'em Ups with swords.
New School is mostly Taito Type X and Naomi games. There are a couple MAME games in there.
I'll eventually get around to posting my gamelists.
