I only have about 50 hours in DRG, but I find it really fun. I think it's because there's usually so much to do - 2 weekly quests, 2 deep dives, randomly generated terrain, KPI quests, achievements, promotions, weapon upgrade quests, pickaxe and gear quests, season quests etc. Also the extremely low levels of toxicity makes it such an appealing game, I really hope it stays updated for as long as they can. Can't wait for the next season!
You're absolutely right, especially for the low level toxic community. My hope is that they'll move from the lithopage lore arc into something uhm, "newer" lore-wise.
