Games Blender Works With?

Hey all from another Blender noob. I’m trying to find what games Blender works with and can do models for. I’ve tried using it with CIV - IV but the NIF script didn’t work (I have no idea why) and all the HL2 model extentions (VTF’s and VTM’s) look like they don’t work with Blender. I’m a tad confused, can anyone help :spin:?
