TSE is a nice engine, but you need to own Torque as well which makes 250$ even with early adopter on TSE (ie no OpenGL only DX at the moment. Thinking that the regular Torque DX implementation is extremely worse and normally results in white objects, I'm not sure if I would trust TSE ...)
I own TGB to create and prototype 2D stuff. due to its level editor, particle editor etc you can get new ideas running far far faster than with BM and if I see that the idea is worth a real implementation I switch to BM ... :-)
