No not at all, not for things like rotating images, you could have a fullscreen image rotating on a sprite no problem together with 2D graphics, it all depends on how experienced with bliz3D you are I would think. If you are just starting out then perhaps it isn's something you want to get right into. There are something called spritemaster in the Blitzcoder showcase which is an easier way of doing 3d sprites but with 2d like commands that you might want to have a look at. Its a blitz code lib. that you just include in your code using the "include" command and then you don't have think about the creation of the 3d entities and all that, you can just use the commands that comes with it just like you would your 2d counterparts.
