Dominion is my favorite game. Created by Donald X. Vaccarino (fucking tight name) it is the first ever "deck-building" game that subsequently went on to inspire an entire genre. Vaccarino has influenced much of table-top card gaming from his work on D&D as well as being a designer for MTG. Dominion works so well as a game, in my opinion, because of its endless amount of possibilities. With 66 x 10^21 combinations of cards, no two games are the same leading to complex and creative brain puzzles to solve. You play against 1-3 other people which, in effect, creates a need for efficiency in building your deck. Otherwise, you are practically doing your own thing while parallel playing with other people which invokes a very wholesome and nontoxic gaming experience. "Attack" cards create interactions with other players but feel less like roadblocks and more like opportunities for unique gameplay. Getting cursed by an opponent's Witch allows for your Storerooms to be more easily and effectively used. Discarding cards from a pesky Militia becomes a sort of engine when you add enough Trails to your deck. Endlessly interesting and quaint, Dominion is a game that has stuck with me for a long time. My best buddy from high school has collected all of the physical expansion boxes and I am always eager to get home to play with the tactile cards. In the meantime, the online version is a simple browser game reminiscent of pi.fyi.
If you're searching for a fun, cool website hosting a genuine and authentic passion project of a game, Dominion is for you.
Let me know if you need someone to teach you or to play with! I would be happy to :)
