After successfully stealing his archrival Mario's castle flawlessly, Wario seemed to be on top of things for once. However, as usual, the good guy triumphs and Wario is defeated and booted out. After blowing off some steam, Wario learned of the Black Sugar Pirates and their leader Cap'n Syrup, and how they plan to unearth an ancient statue of Princess Peach using an almighty genie. Now, we all know Wario wouldn't ever miss and opportunity like this, not only to get his own castle, but to become filthy rich and all-powerful in the process!
Despite being extremely different than it's predecessors, Super Mario Land 3: Wario Land is one of the best Game Boy platformers ever. As Wario, you must travel through a very "Mario" syle overworld and collect coins, defeat bosses, etc.
Wario Land is perhaps best known for it's wide variety of original power-ups, including the Dragon Hat, which can burn enemies and certain blocks, and the Jet/Eagle hat, which can, obviously, give you temporary flight. In the Virtual Boy version, you can even mix-and match hats to create things such as a flying dragon hat, etc.
Wario Land has awesome replay value, the game will keep you coming back again and again. It's fun to go through the game, collecting as much coins as possible, and looking for secrets. This is one of the main reasons this game was so good for a GameBoy game.
Despite it's huge worlds, challenging bosses, and original items, Super Mario Land 3 falls short when it comes to originality. Sure, it features Wario in a new world, with new power-ups and enemies, but when it comes down to it, Wario Land is VERY similiar to Super Mario Land or Super Mario Land 2. This is the main reason Wario Lands 2 and 3 were changed so much.
Despite that, Wario Land remains one of the finest Game Boy games to date, even with Pokémon Gold and Silver out now, and with Game Boy Advance just around the corner.
