Here's my thought on the matter:
Honestly, I could not care less [about where the money raise over and above producing the promised product if there is any] . Seriously, I get a product I already like the beta version of, in a format that is, by todays expenses, worth the basic retail price: 75$. If the extra money goes to Marc and FFE for their 501K, no problem for me. plus, consider how much of the final price of any gaming product does not go tho the actual author - I can easily see it as helping him getting a better than 20% return for each dollar you spend on his product when it goes thru normal production. Basic wholesale is 30 -40% of cover -and ask Matt how much of that gets lost due to every other damned thing before the owner gets paid.
See, I like RPGs, I appreciate the work and passion that goes into them, and the ways they enrich my free time and friendships. Assuming even 75% of the money is over and above the upgraded version that the stretches represent, amortize it over 40 years of RPG design for Marc, and it is a small annuity indeed.
Frankly, too, of the main designers of my favorite hobby, a distressing number of them can hardly be said to have profited by their efforts; and if one of them gets a bit of a bump at the end of his career, well, okay by me. Perhaps that will encourage the next generation when faced with the choice of making a decent living from not doing RPG design work or following their muse, and thus making my life more entertaining. In fact, it represents about a $ 2.50 per person per year 35 year subscription for the 2000 backers alone. Not a bad deal for 35 years of traveller fun; especially given the number of crappy movies and books I've plopped down more than 2.50 (or even 25.00) for in any given year, each of those years.
Honestly, for what we give to creators vs what get, we have a great deal going; and I'm speaking of the whole industry here.
