Missing from this imo is how drastically it all changes with the scale of the numbers involved. If you aren't likely to sell big numbers in the first place you're better off pricing out the people who only buy at low prices since they're also the ones who aggressively refund and write shit reviews
Any advice Tom has on making indie games is worth listening to, but I really want to highlight his thoughts on price point - it's well explained. I do think that the movement to get indies to charge more mostly just hurt new indies - with fewer players, fewer/worse reviews, and lower sales.
