Im a newbie in this scene, but I’m so exited about what i can do and i really want to make my own games, but how can i make things like weapons and armor, houses from the medieval scene, and castles/fortress?

Thx, julian.

To continue where buscas left off, You will need a 3d application to make your stuff in.
Blender is free, then there is 3d studio max, maya, zbrush and many more.

Thank you, guys!!
