Fortnite if you count STW. I don't play it religiously, but it's always been a really original, fun and relaxed long-term PvE game. It's a shame Save The World gets overshadowed by the F2P BR mode. My only gripe with Fortnite is how it forever changed gaming, Epic and killed off Unreal Tournament.
Minecraft is also great, but ut doesn't hold my attention as well.
