While I technically could, I never support a dev with money that in the process of making a game, I support them only after the game has been delivered. When there is a "completed" tag and it looks good will I support them. The one thing I see a lot of, is people who think it is all about money. You don't get into software development to be rich, as you only make money on the back end (typically), when its done, and people like it. The rarified 0.1% which can make a living based on their subscriptions, good for them. The rest of the 99.9%, sorry, that is life.
That being said, there are a few games I will help out with my time. I write walkthroughs and image guides to multiple games that I like. My time is worth a lot (I bill at $500/hr IRL), and if I spend a couple hours a month writing a walkthrough or updating a guide I created, you get the point.
