Quote from tomatobob:
if it's sidescrolling then it's hardly 3d is it?
using your argument: then it is simply 2D.
3D is referring to the graphics, not to the game-logic, but can involve both.
"There are however a number of twists that aren't possible with normal 2D platformers: It is common in such games to let the two-dimensional plane cross itself or other planes on certain points, thus creating "track switches" in the course. Players can explore different areas of the 3D world that way or can be brought back to previous points seamlessy. Interactions with the "background" (non-accessible points in the 3D landscape) are also used extensively."
Another confusing thing, seems "2.5"D is a very broad word and made for big confusion:
You can also achieve these things with sprites and not polygons. Why dont simply bring it on the point by saying "the player is acting on multiple-layers"?
