Dungeon Crawl Stone Soup puts the Playing Game in Role-Playing Game.
It’s the best game ever made. Ok, not really. But good luck finding another strategy game that offers the same level of tactical depth without any of the boring parts.
Dungeon Crawl Stone Soup simultaneously remains a capital T “Traditional Roguelike” and utterly breaks the mold of tradition by actually caring about the player. There is no grinding. There are no tedious, multi-step rituals to accomplish basic tasks in the name of fluff. It is pure tactics. Everything that is not tactics is taken out. If something is not tactics and they can’t take it out, it is automated. It does not require a google search or wiki to play (and beat).
Also it’s free and you can play it in your browser. You have no excuse!
