...I think the difference is New Voyages was a modern-era show set during the 5YM as opposed to STC's very accurate return to the 60s. There were definite references to later series and movies - Carol Marcus, 24th Century Kirk, Spock and Scotty, Ferengi, Borg, the Excelsior, Dr Yar, need I go on? Dare I say Cawley felt that STC stole his spotlight?
For the most part I disagree, on this yes NV had call forwards and took full advantage of using trek actors, but their work felt original and true to TOS, while STC always felt more like a Next Gen episode on a TOS stage but again to each his own...
I never donated on kick starter, but I did donate a few dollars here and there directly, and I headed up to NY for Trekondarogra, so the only thing I can say I was ever owed was thanks for the donation and thanks for buying a ticket and making the trip, which I got so, I can see a donator wanting something for their effort.
