@Andar - Yes, that's right - the $100 goes to charity.
And while I agree it's not a massive amount of money, I don't think we should equate game quality with cash spent. In this industry, you're only ever paying for skills (e.g. artists, programmers, composers, etc.). Sometimes people will work for a very small amount, or perhaps A88mph is friends with people and they'll do the work for free. Nowadays, there's also lots of great open source content that's free for commercial use. And, of course, some people can do almost everything themselves - particularly with an engine like RPG Maker. When you've got a minuscule budget, paying an extra $100 to get onto a service that is very difficult to pass through can be a big expenditure and is very much a risk/reward scenario.
So I can definitely see where A88mph is coming from on this topic, I just don't think it's likely to happen.
