"What the hell kind of game does three-player co-op and no more?"
Most games have multiplayer of some sort. A lot of them are Co-Op Multiplayer
, and arcade games, understandably, tend to have it more than any other video game platform. Most games support either two players or four. Some games, however, only support up to three. Why three? Nobody's really sure, as the Rule of Three
doesn't really work in terms of players.
If these games get home ports, the number of players will usually get either reduced or enhanced, depending on the console and time of release.
