Has all genres covered. Systems are easy to find and usually affordable. Regular joysticks aren't the best. Some of the better games are quite expensive. Many arcade classics not available except with 2600 adapter.
Few games take advantage of the add-ons.
Bad Points Disc is terrible for maze games. Most arcade classics do not exist. No multicart available. I decided not to cover every system due to space constraints and due to my limited exposure to them. Unlike most collecting genres, the older a game is usually the cheaper it is.
