The Rebirth of Maple World! (big bang)

MapleStory is an MMO, and is therefore in a constant state of flux. To argue that this isn't MapleStory doesn't make any sense. Six years ago, MapleStory was four towns and a little dungeon, and skills up to level 70. The game has changed a lot since then, and it will continue to change. Nearly all of the changes to Big Bang are positive; I'm assuming the negativity is mostly coming from resistance to change.

When I started, a little after the third anniversary, GMS already had 4th job and all the continents it has today, even NLC.
A lot has changed since then, of course. Many world tour areas added, Phantom Forest and Crimsonwood keep, Pirates and all the jobs after. But those were additions, not remakes of existing stuff (except for the Vic Island mob rearrangement that came with Monster Book, and a few skill changes with the "rebalancing" patch). And all those changes were gradual.
Here we are talking major restructuring of everything, all at once. Mobs, maps, skills, formulas, quests... Too much for this old dog to accept as still being the same game.
