Rogue-like turn based tactics game with deck building. Set in a post apocalyptic fantasy setting (just like D&D's Dark Sun campaign world), you will be tasked with exploring a map filled with random encounters and boss fights.
The deck building is interesting and the tactics element is appropriately challenging. You will unlock new classes and cards after each playthrough and there are multiple campaigns to play and explore. It's a very generous package.
That said, the rogue-like nature of the game may turn off some as you can't carry over levels and equipment from previous successful runs. Each scenario begins with characters armed with basic equipment and decks and they need to be built up again.
I believe there's potentially many hours of entertainment here, I only stopped playing as I felt it might take over my life as some kind of endlessly replayable (and enjoyable!) game.
