Orna's dev is great! Played that for several months myself. Eventually I burnt out, but it was still a good GPS game. It is however the type of game meant to just be played during your commute or the likes. Basically a Pokemon Go alternative. So it is long and grindy by intent. So it won't satisfy anyone that wants to play a "normal" game where you just play for 10-100 action packed hours and you're done.

But for anyone who enjoyed Pokemon Go, you'll enjoy Orna. It's much more in depth, with traditional RPG classes, equipment to collect, dungeons to find, and raids to do with a guild. The combat is mostly fairly simple, but that's exactly what you need for GPS games, since it's meant to be played on the go. It certainly encouraged me to take more walks and that's the big reason I love GPS games.

The dev is like the anti Niantic. I actually gave him money cause I wanted to. There's no need to pay for anything at all and the game doesn't have nearly as much FOMO as Pokemon Go.
