Use blender?

Should/can i use blender to set out a map for the game im making? Using the shapes that can be added by blender.

Blender is a wonderful option for creating game maps/models. Once you have your models/environment modeled the way you like, you can either use the Blender game engine with or without python (a simple to use, but powerful coding language) to set and create the actual game play or you can export your models/gameworld into one of several game engines such as orge or crystalspace.

kk thanks Dreamsgate!
