Production Line video blog #21 thinking about engines. I talk a little about it in this video, but will blog about it properly soon. basically I want a separate system for putting together engines, but do not want to overcomplicate matters, or for that matter…under complicate them. Interested to know peoples thoughts on this. Also I remain excited about new car body designs, they can’t come soon enough :D. I should blog about promoting and marketing PL at some point too…its definitely something I have not done much work on yet.
