I've been trying to find a CCG (Collecting card game) that is focused moreso on single player, or has a vast single player story. I don't like multiplayer ones, only because you're either forced to buy more cards, or you have to wait extended periods of time for the right cards to make your deck. I'd much rather play a game where I can grind for a specific card(s) that I want within a reasonable amount of time, or by beating opponents with a certain score.The closest game I can think of was HEX: Shards of Fate that sadly got shut down.
Only yugioh comes to mind (the one that let’s you beat all the anime characters)
>>729313835MTG forge is a pretty good community made game and it has plenty of singleplayer modes, sentinels of the multiverse is a capeshit board card game but it has digital adaptation and it's pretty good, has some great mods too and YGO legacy of the duelist lets you play all the duels from the anime out.
