This is a collection of resources I have used and would recommend. Click on the titles to link to the websites. Subscribing and purchasing through these links will also give me an affiliate commission and help fund my games.
Also, check out my collection of Unity assets which I have used and think are useful or cool.
I use elegant themes Divi for this site and I think its a great solution. For the price of a single premier theme you gain access to all of elegant themes. Including many plugins too. The Divi theme is the crown jewel of the collection with a specialised divi builder which makes building websites easy.
Production Crate has a bunch of resources like audio effetcs, music, visual effects and video making templates that I use for my game and help with making marketing resources.
Has free products and a reasonably priced premium membership.
