Hello all! I'll be quick with this. I'm looking for an engine with a ton of assets pre-loaded into it since I don't have the resources to make my own. For example, if I could use the level editor of say, Halo, with all the textures, geometry, and other stuff loaded in, that would be great (kind of like a mod). I'm trying to make levels for 2D and 3D games. I have the latest macbook pro to use. Thank you for reading!
