It's a shame what ended up happening with TemTem. The game just doesn't respect your time at all once you're done with the campaign, there is a crazy amount of grind for no real reward. I thought they were going to take the Pokemon formula and fix the problems with it, instead they mostly compounded them.
Visually the game is great, and I really like the monsters. I do think it's worth the price of the bundle for the campaign alone, just know it goes downhill after. They really want to push this as an MMO and live-service type game with a battlepass, despite the lack of social features and their insistence that no new monsters or islands will be added.
