It may not be a perfect game, but I'm deeply impressed by the raw ambition of XCX.
In an era where much of Nintendo's software output has been, in my humble opinion, stiflingly conservative and safe, (even straight-up lazy at times) this game is everything they've been lacking; it's huge, it's epic, it's complex, it's "hardcore" oriented, and it's not afraid to take risks.
Nintendo needs more games like this.
