Well are there any clear advantages to using a dll rather than having all of your functions in your executible? Is it worth the time and effort? And I''m talking about games here not drivers UraniumRod

sure there are. Say that you want to optimise for a cpu. Oh wait, that is a driver type. Say you want to make your game capable of addons without distributing the core source code. You could also use dll''s for distributing parts of your code that you want to leave open source. Say the rendering dll. It could be ported to software, OpenGL, DirectX. Just a few examples

Or maybe there''s a terrible bug in one of your .dlls. You just fix the bug, compile the new dll and upload it. That way users that have already downloaded (or bought) the game just have to download one file instead of the entire game.
