This is absolutely true. Only Beast Wars has ever even come close to Marvel G1 and G2. And re: the topic, Dreamwave will never be worth money because supply will always exceed demand. The last ten issues of Marvel US are allegedly worth huge money on the secondary market at the moment though. The Overstreet Price Guide has them worth up to $50 and, for some reason, Wizard is claiming that #80 is worth hundreds. Although for me those issues have far greater sentimental value. When issue #79 ended with 'All Good Things... See Letters Page', my heart literally stopped. After being a part of my life for seven years it was going to be gone forever (as far as I knew) and the final story arc was (for me) the best since Target 2006.
The idea that there would be Transformers comics seventeen years later was inconceivable.
