`  == Extremely confusing article that collates far too much information ==  This article contains a wide variety of valid information, but it's not particularly clear why it is collected together.   There is little to no linkage between these topics. What does parallax have to do with bump-mapping? Or axonometric projection with Trine 2? If these are different concepts that all share a term, we should have a disambiguation page that points to ``2.5D graphics``, ``2.5D engines``, ``2.5D gameplay``, etc. If this is supposed to be a catch-all page to describe all means of representing 3 dimensions in 2, it should be titled more appropriately (``Pseudo-3D`` might work) or some sources need to be be cited as evidence that ``2.5D`` is indeed used in that catch-all sense.  The colloquial term ``2.5D`` as it is used in the current gaming discourse *almost always* means ``2D sidescrolling gameplay in a 3D environment``. See  http://www.giantbomb.com/25d/3015-660/games/ http://www.raywenderlich.com/4551/how-to-make-a-2-5d-game-with-unity-tutorial-part-1 http://gamedev.stackexchange.com/questions/tagged/2.5d http://forums.steampowered.com/forums/showthread.php?t=1723480  And that's all from the first page of a Google search for ``2.5D games``. If that is the most popular current usage of the term, why is Wikipedia evidencing something different?   It seems clear that 90% of this article is about various topics (such as graphical projections of 3D environments into 2D), which - even if it has been called 2.5D, which none of the sources suggest - are clearly separate from the topic of games set in 3D spaces that restrict movement to a 2D surface. I cannot see any reason that these topics should be combined under the banner of ``2.5D`` when no cited sources combine them. This seems very close to Wikipedia inventing/redefining a term. If I'm wrong, we need some citations using the term 2.5D to describe both games like Lincity AND New Super Mario Brothers in the same breath.   Otherwise, they are two separate topics and this page should be divided at the very least into two articles, one for ``Pseudo-3D graphics`` and another for ``2.5D games``.   `
