From scratch, so I don't have to play your second-rate Project M reject mods.
Oh yeah, because Smash Reborn is such a fun mod "made from scratch." If I wanted to play Easy Mode Smash I'd just play vBrawl. This is coming from the person who thought giving Dr. Mario F.L.U.D.D. was a good idea.
Don't come in here calling any of this work second-rate: work IS put into this no matter the magnitude, and it's actually pretty intriguing and ingenuitive, expanding on an idea that is frowned upon, and this is because the creator WANTS to expand on it. That's the kicker, this isn't what YOU want, it's what HE wants. And you aren't helping in the slightest, contrary to what you think. Project M is the base, and that's that; I fail to see the issue with that.
You also fail to realize that not everyone is gifted with the ability to write the codes featured in PM or any full-game mod, and the PM devs had a team to do it; no one person wrote all of those codes themselves. If the goal is to write all new codes from scratch as you're suggesting, that goal is certainly not here. Again, a choice by the creator, and again, I fail to see what the issue is exactly with it.
You're a prime example of what's wrong with this community: you want and you want and you want, but when it's not what you want you suggest ideas that you want to stick, then get defensive when people disagree. Now granted, everyone can be like that, but that doesn't mean there won't be people against you for it. People forget it is in fact possible to mind their own business and move on; this mod isn't for you, clearly, so why try to "help" it? Why is there the need to "show" the creator or anyone else that it's inherently "wrong" to use something someone else did as the base for something like this? Project M was built for this type of thing, so there's literally no problem with it aside from whatever your own issues are. Keep those to yourself and let people work as they will.
