I’m enjoying NecroMerger. It has optional ads (no forced short ads either) and the micro transactions are either some general buffs, ad-free version or gems. The gems are dished out royally imo, where I’ve purchased most of the premium currency content by just playing.
Something you can’t play right now but can sign up to play for later: WalkScape. It’s an RPG game in a similar style to RuneScape, but you actually have to walk to craft, skill and walk around the map.
The team has often said that they are against microtransactions and other monetization schemes that currently plague the industry, so they have plans to release a freemium version and a paid version.
