Many of my fellow gamers look down on the "set-it-and-forget-it" style of social freemium games, but I have a soft spot in my heart for them. For me, the genre's appeal started with We Rule a few years ago, and continued with Battle Nations and Dragonvale. There's a definite addictiveness and appeal to real-time based gameplay.
Kingdoms of Camelot: Battle for the North by Kabam won't change your opinion of the genre, but it represents its strong points well.
This is Kabam's first iOS title, though the company has titles on Facebook and in browsers. Don't confuse this game with the group's other game called Kingdoms of Camelot. Kingdoms of Camelot: Battle for the North is a brand new title, designed specifically for mobile devices.
My main issue with it is that it looks bad on the iPad. It seems like it was designed for a much smaller screen. But the UI is still clean and simple, and the game's quests intelligently lead you through what needs to be done. As you play, you can interact with other players. Kabam's experience with social networks undoubtedly accounts for how nice that experience is.
Kingdoms of Camelot probably won't change your world (especially if you've already decided that you dislike this type of game), but if haven't tried this genre, it's worth your time. Who knows, perhaps you'll find yourself getting invested in all of the cottages, farms, and barracks that slowly become grow burgeoning empire.
