There are a lot of P2E games out there, it depends on your preference.
If you are looking for FPS kind of project, Undeadblock might be suitable for you. Not only do they have a good community and development, but they are also running on a good platform IMMUTABLE X. The game is similar to left4dead, we are shooting zombies and getting their native token through it.
If you are into strategy and turn-based games, you can try Splinterlands, GodUnchained, and Skyweaver. They have been in here for years and they never stop developing their project.
Undeadblock is an interesting game, but quite resource-intensive. Not every PC will be able to run it

I don't see how this game is graphically intense, it looks like something a hd4000 gpu can handle very well at a higher resolution like a 1080p display, you can't compare this game to the graphic details of illuvium, Undeadblock looks like a 2012 graphic design game.
