Is it a good idea for Nexon to make a pre-BB server? Would you care?

I for one think it's a great idea, other games have taken similar routes. I'm not really sure what everyone's complaining about. You DON'T have to play; this is not a replacement of new Maplestory, simply an alternative. There is a market out there for something like this, whether Nexon decides to hop on it or not is another story.

Complaints are valid because this would take resources from Nexon better spent elswhere.

A handful of people might love this and no life themselves to death forever and ever, but most will burst with nostalgic hype for a few days and then ask themselves what the hell they really thought they'd do with it.
And those that are not veteran players would puke blood all over it because of how grindy and content lacking it is compared to the modern incarnation.

I think the term anticlimatic best describes how this would end up.
