She's already tried Puzzle & Dragons and didn't care for it.
I'm not a fan of "clickers" or games with very little actual gameplay (sorry, Final Fantasy Brave Exvius fans and Brave Frontier fans) or strategy RPGs on mobile. CCGs (collectible card games) are right out. I'm not at all opposed to a one-time purchase if it means avoiding all the rubbish that usually comes with free-to-play titles (e.g. slot machine gachas, stamina systems, mind-numbingly repetitive grinding, etc.).
MS, despite its flaws, filled a very specific niche and we really enjoyed playing it together. I'm going to miss playing it with my wife and older daughter.
And while we're hoping to play PC games together again someday (we'll be back, Guild Wars 2!), we're just not in a season of life where we can do that right now.
