***QUESTION***
why use 2d in 3d when you could do renderworld and then do plain ole 2d on top of it?
***ANSWER***
Some cards slow down majorly on 2d over 3d graphics, and alot of cards do it slower. Its partially a speed issue. Also, you can do cool effects like alpha, realtime rotation, scaling, etc.
Besides speed (which is a big issue) consider also resolution independence. A HUD done with 2D graphics commands won't be scalable to the player changing the resolution of the game, while a 2D-in-3D system won't care what resolution the game is set to.
I think BR needs a Blitz beginner FAQ section for just these things entitled BLITZ NEWBIE FAQ.
