Just personally they arent my type of game. Single player games are my forte
I think so too on the Overwatch DOTA hybrid, it makes sense they are making MOBA/Royale style games since that's what's popular (esp internationally) and what makes money. But again, not my genre.
I've sunk many hours into the game. It rarely goes on discount but I and many other players have found the price tag pays for the hours of content it provides many times over
P.S I find the newer caves to be much more challenging and certainly more interesting than the old caves. Plus you can just not use the recipe book and play on hard or hardcore mode
