it isn't a straw man argument, you can't say "well indies/crowdfunded titles should be AAA grade" and then trn around and say "why doesn't someone make a game for PC that's good". in doing the first statement you lock yourself out of a massive group of devs that would gladly deliver that pc experience but hey, they can't make it because you have some an irrational reason (time to release) barring them from doing so. you don't get to have your cake and eat it too.
plus why do you care so much how long it takes a crowdfunded game to complete? oh no, a crowdfunded game took 5-7 years to make! what difference does it make? the argument you've made in previous threads on SC of "well they could have made X number of smaller games" is also completely irrational as Chris Roberts created CIG specifically to make SC, not a dozen greenlight games for early access on steam. so again, what logical reason is there to say "they shouldn't try this"?
