Now look, I don't tend to particularly enjoy OSR games. I got into RPGs in the early 2000s and the vagaries of older editions of D&D don't hold much nostalgia for me. That said, I love the hell out of this game. In fact, Godbound might very well be my very favorite RPG product at the moment.
The system is pretty simple, like OSR tends to be, but it avoids all the parts of OSR that annoy me. There are no pointless limits on character power based on arbitrary things (like Race in old D&D), THAC0 isn't a thing, and every little thing doesn't have its own tiny system.
Instead what you've got is a slick interface, a somewhat non-standard Damage/HitDie mechanic that gives the game a vaguely cinematic feel once you grok it (read the combat section thoroughly, it's different), and just the overall FEEL of being... powerful.
Godbound wield the Words of Creation, little-big packets of divinity that give them access to powers that make you feel legimitately like a deity, kicking over nations or founding them, stomping horros from beyond, you name it.
The deluxe version is totally worth it too. The extra rules give you gudielines for expanding the scope of your game and even make it easy to translate in some of the feel of... other popular god-games that've been making the rounds of late.
I backed the Kickstarter for Godbound and I totally don't regret it. Kevin Crawford (Sine Nomine) is probably my favorite RPG producer at the moment. You should at least check out this free version of the game, it's super fun. And once you fall in love with that, toss him some cash and get yourself a proper book, why not? You won't regret it. This game is my new happy place.
