osu! is a great game to play in your free time. Being a rhythm game based off songs, it doesn't require you to commit to long playing sessions like MOBAs such as League/DotA/Smite, features solo and multiplayer (head-to-head) play, and essentially endless songs and difficulties to keep you playing for as long as you'd like - seriously. There are hundreds of thousands of songs in every genre; the vast majority being Japanese rock/Vocaloid/electronic, but there is more than enough music of every English genre out there to satisfy everyone. There will be songs and difficulties perfect for everyone, and due to the nature of that, the replayability is endless despite the same general style of gameplay. If clicking circles and sliding sliders isn't your thing, there are also other modes like osu!mania (Guitar Hero-esque), Taiko (drum rhythm), and Catch the Fruit (literally catching fruit on a platform) that will satisfy you. In addition, it has been getting widespread recognition and popularity due to popular streamers on Twitch praising the game for its compactness and its ability to strengthen your mechanical skills on other games due to it forcing you to improve in areas such as muscle memory, reaction time, screen vision and so forth. Here's a League player's standpoint of how osu! improves his League gameplay: http://cloth5.com/10-reasons-you-should-be-playing-osu/ Customizability also never ceases due to the ability to create your own beatmaps for others to play (99.99% of beatmaps are actually community-created!), skins for the game you can create for yourself and others, and so forth. There's something for everyone.

But seriously, if you're into music and playing very relaxing and chill-atmosphere'd games, then I strongly recommend that you try osu! - I've discovered some incredible music, incredible artists, and made a ton of friends in this game. I downloaded this game a year or so ago and recently picked it up again this August, and even though I'm not too great in the scheme of high-level players like Cookiezi and rrtyui since I've only actually been playing for a little over a month (I only have like a third of Killua's playtime ), I'm having so much fun playing this game and it's easily made its way into some of my favorite games of all time. Oh, and did I mention? It's completely free. No subscriptions, no initial cost, no sneaky in-game purchases that tempt you like Gralat packs or League of Legends skins - it's all free. You can however, pay a few bucks a year as a donation (I do, very grateful for this game) for some neat features like downloading maps from inside the client and a tiny bit more files to skin, but it's all unnecessary to play this game to the fullest.
