Of all games I’ve played over the past year or more, I’ve played Kingdom and the New Lands expansion the most. I can best describe Kingdom as a one dimensional simulation game. The only way to move on the island is left/right while riding your mount. Along the way recruit troops, build an encampment and walls, defend your encampment, and try to get off the island. Remarkably simple, yet I have over 200 hours into the game, it’s very sticky and repeatable.
I’ve been beta testing the mobile version for a few months now and have come to love it more than the desktop version. I’m not 100% sure I agree with the way progress is saved on mobile (only at the dawn of a new day), but it’s has worked out well to save me a couple times. Well worth the download to see what a sim game can really be on mobile.
