Maple Story 3D and Maple Story 2. Does not seem like a hoax.

The graphics actually are more impressive than Dragonica (Well, to me), but those examples of gameplay make it look really slow and unexciting. But well the whole fighting bosses that are in the background thing is kinda cool.

The graphics don't matter to me much, considering I appreciate a game like MS. (LOL)
And in Dragonica, the first major boss, Lavalon, is in the background as well. ;x



I also noticed that the MS finger cursor is chilling in Kavatina in the second video.
