Okay .. i will explain ...
i belive that the already made templates comes like limit template ...
so if i have an idea to create a game which depend on a story of a special theme ...
- example : if i want to start a car racing ... for sure i will draw and plan
all the plan and idea for the game map before start the game project..
- Another exmple, if i have idea to create a RPG game like the old version of
DOOM, i would design a whole map of the game depends on the game theme of
story, which is means the way i i designed the game map itself.

In somple way ... can i do something regarding to my MAP or i have something which let me stay in limnit ?

This is all because i only do graphic design and modeling .

Regards
