So, I quit Hearthstone recently. Not just because of current events, but because I lost my taste for the game. Which is a shame, because Hearthstone is pretty well made and what it simplifies from Magic the Gathering and comparible card games is pretty inspired.
Couple things I Liked
You pick one class when you create a deck, and your resource management is doled out every turn without intervention or having to worry about Mana Burn or Flood.
It had a sort of chess by mail setup, where you couldn't really interrupt your opponents turn without laying a Secret trap for them that would trigger when a condition was met. I appreciated that you weren't on the clock for having to play an interrupt or cancel an opponent's move, especially since I mostly play on mobile.
Finally, it had one of the best UI for getting things done, and letting you know where you wanted to know. The main menu was organized, the deck builder was clean, and the playmat was very polished with the oval minion pieces, while informative on what everything did. I've been trying Eternal recently, and it's certainly an adjustment.
But to prevent this from being a one sided breakup post, I ask you, dear Tildos, what would you want out of a Digital Card Game? Be it a weird mechanic, playing mode, ideal platform or like this except with that, what would keep you coming back to such a game?
