Taiko has, from the beginning, been a very social game. On the arcade (in the older models at least), players are encouraged to play together; if one player fails, the other more skilled player can save his round and both can continue. Then there are co-op notes like Yam, Kusudama and the Double note. On the console, multiplayer is encouraged too, with minigames in several versions, 4 player versus supported by a single copy of Taiko DS or 3DS, and Miiverse integration on the Wii U.
What do you think could be done more to innovate on connecting Taiko games together?
The first thing that probably comes to everyone's mind is score-sharing. Local scoreboards are present on Taiko Wii, PSP and Wii U, but what about sharing scores online with friends? Assuming you're not in contact with perfect godlike players all the time, attacking each other's scores could be a great motivation to play Taiko.
Costume-sharing is done on Wii U through Miiverse, but what if you could visit other player's games with your Don-chan character and help them do certain things, like clones in PSPDX's story mode or, on a larger scale, a sidequest/collect-a-thon like in 3DS' Streetpass Mii Plaza?
Speaking of which, Streetpass would be a great idea to implement new communication ideas between Taiko, and a lot of cool new modes could come out of it. I can already think of the possibilities!
Any ideas from you guys?
