I would be curious about your favorite coop games. I often find them a big lacking, often being a bit unbalanced. An example is Battle for Hogwarts, where one game can be a walk in the park and another absolutely impossible and rarely is there a balanced match.
Sounds interesting, I kinda like dungeon crawlers. Its probably a remnant of playing diablo2 when I was younger. I will have to check it out. Do you prefer 1 player or 2?
I basically only play it with my SO so can't comment on single player.
From scanning the rules, the campaign sets certain events and "layouts" for certain levels and consecutive runs. It also adds a little bit of meta progression to give your character's two abilities a bit of variety.
portable mashes well with our lifestyle, we are very much on the move. At most places we have already stashed some games but often bring 1/2 with us as well
