My family and friends have become addicted to Words With Friends. I think the combination of turn-based gaming with push notifications is the key. So what's next? Are there any other games (besides Chess With Friends) that are doing it this well?
Me tooasynchronous multiplayerWords With Friends made me a fan! UniWar does it tooits a sci-fi strategy board game, fairly complex but with in-game guides and tutorials. I havent gotten into it as far as Id like (been playing other games) but it has been fun. You can play through a single-player campaign to learn the ropes.
