I love teardown, but it has a long way to go (with plenty of ceiling for growth). After playing teardown for an hour I couldn't wait to start modding. I downloaded around 100 vehicles from different users and then built out a killer vehicle level. This took a few days of learning the ropes and I was about to upload to share....but then I think I read I cannot share combined elements from various users. Is this true? Please let me know.
