Nintendo is mining its back catalog of 8-bit hits for re-release on the Nintendo 3DS. Two games, Excitebike and Xevious have been released - the latter only in Japan - as part of Nintendo's 3D Classics line. After that... Urban Champion.
If the name Urban Champion isn't ringing any bells, it's a Famicom/NES head-to-head beat 'em up dating back to 1984. The NES version is available via the Wii Virtual Console, which you'll find is not very good. Regardless of its quality or status as an actual "classic" game, the 3DS version will hit Japan next month, July 13, for ¥600 ($7).
Clearly, Nintendo is pacing themselves with its 3D Classics releases. You don't want to just toss up all the good stuff on the eShop all at once, right? Give 'em a few years. They'll get to Clu Clu Land eventually.
