In a typical metroidvania, the world you play in is all interconnected. One game made for the Virtual Boy, which by all accounts is one of maybe two worth owning the system for, and a direct sequel named Wario Land II in nineteen ninety eight with an updated Game Boy Color version playable on a regular Game Boy later that year. The game was popular enough for a franchise to be made. Oh, spoilers for a game over twenty years old, by the way. The game starred Wario as the main character and decided to do its own thing while leaving almost any trace of Mario behind with one notable exception at the end. Two years later, the world was introduced to the third game in the Super Mario Land series which also carried the subtitle Wario Land. The name Wario happens to be a portmanteau of the Japanese word warui, which in English means bad, and the name Mario making Wario a bad Mario as it were. The second game in the series released in nineteen ninety two, subtitled The Six Golden Coins, introduced the world to Mario's evil counterpart Wario. Meanwhile, in the year nineteen eighty nine, the game Super Mario Land was released for the original Game Boy.
