Isometric is 3D - right?? So if you do a game in isometric does it need a
3D 
engine??
<

It could be, but it doesn't need to be. 2D engines can be equally
isometric. As mentioned, it just means that equal (iso) distances (metric)
in the world (whether 3D or 2D or 1D) translate to equal distances on the
viewing surface. First person isn't isometric (I suppose it could be, but
it would be weird, like running Quake with a very low FOV) because it
performs a perspective divide, so some object will appear different sizes
depending on how far away it is. A 3D isometric engine just ignores the
depth of an object when projecting it. A tile-based game is isometric (a
special case where everything lines up with the screen.) Generally
third-person views use this. The Sims, for example, is an isometric engine
in 3D, while SimCity 2000 is an isometric engine in 2D (both AFAI can
tell.)
