I've known about this one for a while. I tend to forget to mention it when listing free tools because it's pretty forgettable. It's nice and all but not as good a modeler as Wings3D and not tremendously good for much else. With respect to Blitz game creation that is; it doesn't have any good tools for texture mapping and it cannot export any animated file formats. It IS a pretty good choice for pre-rendered animation like FMV cinema sequences, but then for not too much you can purchase a better tool for that purpose.
