UK App Store has Ludwig and Suburbia at full price ????
It's showing up full price in the US store for me. Must've been a really short sale.
Haven't tried it on mobile, but I purchased One Deck Dungeon on Steam last week and blew almost 4 hours into during my first sitting. It's a really good dice game. As with any game involving dice some luck is involved, but it's not nearly as merciless as a game like Talisman. Kind of reminds me of Pathfinder Adventures, but without the RNG of card management on top of your dice management.
Even at the full Steam PC price of $10 I feel like I got a bargain. Will probably pick it up on mobile for some on-the-go play.
