When making a game... (C#/XNA or C++/DirectX)?

When making a game, is it better to draw the terrain in the program using vertices, or in 3d max and importing it?

I think that it is better to draw the terrain using vertices b/c importing terrain could put a virus on your computer.
Reply:Well it depends how you draw those vertices.





Typically its better to have those imported things from a model made in max or maya, because the vertex importers are more optimized.





If it is a small object you are drawing, using your own vertices wuold be good as it will save you some time.
