I have it both on emulator and the real game. I use the emulator to play online. Even though ever since brawls release, the online area isn't as big as it used to be.
Its much more difficult than both of its sequels. Like for example, air dodging. Melee had on air dodge, but if you're still in thei air, it counts as your third jump. Brawl has an infinite amount of air dodges (as long as you stay in the air). And the original has no air dodges, so your only choice of defense in the air is a good offense. Plus its minimum of cheap moves is great. The only thing you could really spam that I can think of at the top of my head is Mario and Luigi's fire ball, and pikachus thundershock. Unlike the other two which I won't make the list because I'm lazy.
Also, edgehogging is nearly useless in the game, so no one really does it. Recovery seemed alot better too (especially for Ness). Plus... This is probably my favorite thing of all. NO FINAL DESTINATION! That makes me happy! Hyrule Castle for the win!
I don't feel like typing any more. so I'll just read posts now.
