angelic crest and wonderland online are created by the same creators they are not the same thing.
with 2 diffrent stories. one takes place in the future with you going to some prestigue school and with mecha suits.

while one takes place in the past with you lost on a deserted island with... coconuts

but i think they shoudl impliment the same type of idea for quests and npc and grapic yea.

but both games are know as 2.5 D
not 2D and not 3D either but with a mix of both.
