Even this makes sense. Put Preorders up for a set amount of time. Have people pay in advance and make them to order through the number of preorders. That way everyone that wants a copy of whatever game can have a copy.
The more legitimate reason they gave is that they wanted to produce in advance so there was no delay between the sale and it shipping. I think many of us, their target market would wait. Hell, I waited years for my dreamcast copy of Pier Solar to finally show up.
You're absolutely right, most people would be willing to wait. But you're forgetting that a company [especially a small one] takes on a ton of overhead and risk doing preorders. It's not just 'more work', it's a lot more work, and a lot more risk.
What if a print batch is bad? Or a thousand other things that might go wrong go wrong? Taking money in advance has inherent risk and creates potential issues that taking money for product in hand does not. Not to mention, just with workload you're increasing it considerably -- rather than ship and forget, you're now dealing with more problems -- people unhappy waiting, cancellations, etc.
You have four releases in the pipeline (two versions of Saturday Morning RPG and two of Cosmic Star), why not just sell a test subscription to those four at $120?
Taking $120 from everyone in advance, before you have product in hand, is risk. So much risk. What if a publisher pulls out, making the promised 4 no longer possible? Plus all the issues pre-ordering itself brings.
Doing a small, controlled print run of a # of copies you're comfortable fronting the money for is, by far, the safest and easiest way to go about what they are doing. Risk is defined up front [the number of copies being printed, in case of a bad print run] and it's by far the easiest workload wise -- take orders, ship the next day. Done.
The more complex ideas -- taking preorders, subscriptions, etc. might sound good in paper but they add a ton of risk and overhead for a small company. Can it be done? Sure. But it doesn't mean it's worthwhile compared to the simple and relatively safe system they use now.
