Jeebus, I wouldn't expect anyone to OPPOSE this idea. Why would you be against something that so obviously would be designed to make things more fun? They're options. Don't like them, don't use them, and it's always a good idea to give as many options as possible, as long is it wouldn't clog up anything. And, of course, this wouldn't since it'd all be in a separate menu than the legitimate match options. I have been aiming for this every since I started playing Melee, and there was a thread wayyyy back when about this.
I think Special Melee should just be an option, and from there you can edit all the things you want to put in i.e. 2x speed Metal small match with low gravity. Then, in the actual character selection screen, you can click on your character and access the special handicaps menu where you can choose to alter your characters' basic stats as you want as well as change their starting conditions such as metal/cloaked etc.
Thesage: I think we all understand why tournament matches are the way they are... people are just referring to the fact that there are many people on the forums who immediately insult non-tourney things such as items or stages that do interesting, different things. Even if you like to have fun, it seems that many do not... as is evident with people who can't seem to understand why you'd want to be able to do what this thread proposes.
Playing a game because it's fun? Balderdash! Sure, Smash Bros. is unique because it is the most customizable fighting game out there... but we don't like options to change gameplay and keep it interesting. No no.
