I like to think of it as ‘crowd funding’ ASL-style. If it helps TPP’s get their product to market, good on them; and it keeps our hobby moving forward.
A wise option, as $90+ is not cheap; those who can afford it (and 'completists') can pave the way for the rest of us, provided decent AAR's and reviews are posted online.
I love the concept of Brevity Assault's operational play, but I'm not a desert ASL fan. I will be intrigued by the reviews to come out and other peoples thoughts on how it plays. Even so, I'll probably wait until an ETO version of the operational game comes out in the future (hopefully early Eastern front, 1941-42 [hint, hint, my Italian friends])
