I've been on here 2 months just over 800 views. 83 downloads and made $33. I've done a lot of advertising though. A lot of retro gaming forums is where my views come from. My games have been DOS games and retro unity games. I'm talking unity 2.6! From 2007. Plus I've made some soundtracks aswell and marketed them as table top RPG atmospheric tracks. So I've had a lot of D&D players download. It's all FREE to or pay what you want! Trying to make niche games has definitely helped.
I'll edit I'm actually using old hardware aswell a 2009 macbook and a 2004 g4 powerbook. Even used Mac os9 for my soundtracks. Not flexing here but I'll note the Powerbook cost me 10 bucks at a garage sale!
