Probably the only Massively Multiplayer Online game that your mom would love, and for good reason, yet it still appeals to gamers. At its core, it's a collectathon that relies on the beauty of its maps, music and ambiance to make the collecting enjoyable. It also lets all players work together to accomplish this goal, and others, which leads into the top notch MMO mechanics - people can't even see your outfit without your consent. Then, if you do consent to that, you can consent to being allowed to add each other as friends, allowing you to hold hands and adventure together easier. Then, you can high five, or hug. It's only after that that you can finally talk to each other! Most importantly, you can stop at any point in this process, and still have fulfilling relationships. Sometimes, you have a friend who's never spoken a single word, and you just play together, and it works. This is by far the most pro-player practice I've ever seen in a multiplayer game, and it needs to be adopted elsewhere.
The story works as both an ongoing saga and a single experience, so if you don't want to get into this, I still recommend "beating" it - you can uninstall after and still have had an excellent experience, no money required. In fact, that may be smarter, since the game can definitely encourage players to spend a lot on aesthetic IAPs. They don't use gambling mechanics or manipulation, but there's a lot to buy, for those who have to have it all.
Overall, though, I wouldn't trade my memories made in Sky for anything. It's a beautiful place that attracts respectful and interesting people - especially ones who you never would have met otherwise, due to the translation features and global appeal. I can't recommend it highly enough.
