The ultimate Nintendo battle
My personal favorite mode would have to be Adventure. In this awesome mode, you go through one level for each character. Mario's level is like the Super Mario games, complete with goombas and koopas. Samus' level is a battle with the famous bounty hunter herself, then escaping from the level, Metroid style. There is another mode, but it is an unlockable, so I don't wanna spoil the secret, altough it's not very exciting.
Next up, event mode. Event mode levels range from a traditional pokemone battle, to battling on top of a giant trophy. Yay. Stadium is actually the home to 2 secret levels and one secret character, though they aren't easy. Training is self explanitory. I hope. If you don't know what training mode is, you haven't played enough games. Really, is this your 1st game? HUH!?
Back to the topic. Versus mode is the awesomness. You battle with friends or bots in Melee, have a...well...tournament in tournament mode, and have fun with the crrrrazy modes in Special Melee.
Now, if you've been playing AT ALL you should have unlocked some trophys. The trophys are beutifully rendered characters and objects of things from past Nintendo games. With each trophy comes a short explanation of what it is.
There are many secrets in this game, each well worth finding. If you look hard enough you may just find 3 secret N64 levels...well, lookings not the problem, FIGHTING WIRE FRAMES FOR FREAKIN' 15 MINUTES IS. Thank you for your time.
