13th Age is wonder. A love letter to DnD made by people who worked on DND 3.5 and 4. 13th Age 2nd edition is in the world now but it's all going to be backwards compatible so there is no reason to not dive in now for anyone interested.
Shadow of the Weird Wizard, too, which is from the creator of Shadow of the Demon Lord, but higher-powered and more classic fantasy rather than grimdark.
