I think it would be cool if there were more subgames added. Small, easy to code things that could help you out with some electrum or a card.
Think back to Super Mario 3 for Nintendo (hopefully I am remembering this right). At various points in the game you would play mini games and win cards that you could use for various purposes.
For example, one game was a slot machine, just like we use after winning a match. However you actually had to hit a button to stop a slot from turning so there was a little more skill involved than just watching.
Another was memory. You had 3 tries to match 2 cards from a pile of 24 that were face down. If you correctly flip over two of the same card, you win them. You could win 3 cards in this way (or 0). If you understand the game memory this should make sense.
Another was "Pick a treasure Chest". Basically pick 1 door of 3 possible doors and win what is behind it.
I have no coding knowledge but these don't seem like unrealistic minigames to add to the game.
If there is a weekly quest, this would be a cool way to win cards. Or if you have a winning streak of X games in a row, you get to play pick a treasure chest. Or everytime you beat a false god, you get to play memory.
What do you all think?
