Prismata, Free on Steam · 9:13pm May 18th, 2018
Now here's a rarity: an early-access game that's being given away for free. A 'kill the servers weekend,' as they put it.
And even more shocking, it actually looks really promising. A card-game with a really neat sci-fi take on the genera, and that's intentionally trying to avoid the Magic standard by mixing some RTS style stuff in.
