Before I begin, let me say that I have no connection to Mantic and have no idea what their plans are for any hypothetical Warpath Kickstarter drive, should they exist. I merely want to discuss some ideas.
First of all, I hope Mantic waits a year or so before starting another Kickstarter. I've pledged a lot to KoW (and to Sedition Wars), leaving me with no more funds until after Christmas. Many others seem to have blown their modelling budgets on KoW as well, so a year will give time to raise more funds. Also, it might be a good idea to let some time pass so that people get to see the results of this KS (and also to grow bored with their SW figures).
Second, I hope Mantic prepares a more thorough range of concept art and even some prototypes to help give a clearer picture of what customers are "buying" with their support. Perhaps Mantic can attach some sculpter's names to specific lines or kits to drum up their fanbases.
Third, Mantic should include at least one "true" plastic goal in their Warpath Kickstarter. There is a lot of demand for "true" plastic out there, but Mantic did not do enough to tap it with the FF and Marauder sprues, which were disappointing (fantasy sprues with Sci Fi bits...sigh). Personally, I find plastic so much easier to work with than restic that I will continue buying DFG and WGF kits over Mantic's Corporation for the foreseeable future. (My experience assembling my corporation troops was very frustrating. And the results were not superior enough to the competition to warrant any more Corp purchases.)
Other than that, I have no qualms about Mantic's Kickstarter performance. They know how to drive a mean bargain.
What do you think they should add or change?
