Searched around and found that the last thread for Osu! had its' last post 2 years ago, so I'm making a new- and dedicated- thread to this game.
The game(takes you directly to download page) is pretty good, all you really need is a mouse, or, for some of the harder difficulties in a song, you would somewhat need a tablet of sorts, but still very possible with any kind of mouse.
In my opinion, the really cool thing about Osu! is not the songs, but how they are made. Creating difficulties for songs -also known as beatmaps- Can give you a good challenge to do if your hand begins you hurt from all the button mashing and spinning. They are also very Fun to make as you can make some funny pictures out of a set of combos.
The other thing about beatmaps if that you don't always have to make your own. You can also
download other players' beatmaps seperately, or if you have a RAR extraction program(WinRAR or 7-zip), you can also download
beatmap packs, this is usually the best idea, as you can only download 3-4 beatmaps in a 5 min timespan, where you can get about 10-12 all at once and beginning to download the next pack without ever waiting.
Osu! also has a multiplayer function, and even in the lobby for the room you joined, you don't have the song the host picked to play, there is a download button which takes you directly to the page of that beatmap and you can download it from there. Osu! automaticly loads all your downloaded beatmaps and prepares them for use.
There are also
skins you can download from the Osu! forums. Think of them as texture packs in Minecraft: they change the way everything looks, from all the circles and spinners, to the scoreboard and your mouse icon.
So, I think that covers just about everything.
DISCUSS!
