Calling Armed a casual game may be a stretch, but as legions of adoring Windows Phone 8 fans can attest, this game's a blast despite being a bit more complicated than Minesweeper (which is also available in the Windows Store, if you're interested). This strategy game skimps on story to focus on meaty turn-based warfare, pitting you against an opponent in a fight to the death.
Command & Conquer veterans will feel right at home battling over resources, building factories, and carefully crafting an army of mixed combat units. The graphics rock, the music rocks, the multiplayer rocks, and the game rocks. 'Nuff said. The title gives you one map free; unlocking the rest costs $4.
