Not going to lie I have an itching to play some Polemon and I may just buy the DLC - despite being negative towards it on here.
It's still early impressions for me but dynamax adventures is probably the best you can get for turn based combat.
You team up with 3 others, you have to pick from a random list of pokemon, first player picks, their pick gets replaced with another random pokemon until you each have one picked. And that's your line-up.
And then it's successive dynamax battles based on a path branch your team votes on after each fight. Each dynamax creature you kill your team has option to catch and trade in for your starter pokemon. You don't automatically heal and regain PP at the end of each battle. Your team has 4 deaths for the entire adventure so you want to get to the final battle with all 4 intact (or at least 3) and the moves you need to beat the boss (and it will take a considerable number of turns).
Some paths will heal you after battle, some do nothing, some have a person that allows you to pick from 1 of 4 holdable items.
I've been in a couple "easy" wins and 2 pretty close ones.
And lets say you already have the perfect Lugia for example - you can pick from any other Dynamax Pokemon caught in the raid. So if I already had Lugia I could have picked up a Dragonair and gotten Dragonite.
I'm not sure about the story yet because I only got so far to unlock dynamax adventures and have been doing that as time allows.
Now is this feature alone worth $30? No but I think it's a good mode, a good implementation and devs should hear the positives and not just negatives. We'll see if there's enough story and other content that I can look at the 2 expansions and honestly say if it's worth $30 or not.
