Castlevania. Finally making its appearance on the Japanese Virtual Console, Konami's side-scroller is a must-buy. I personally consider "liking Castlevania a lot" as an important component of my personality. What an awesome night to have a curse.
Like Castlevania, Power Sports and Dead Moon have both already arrived in the US (Power Sports as World Sports Competition), and Ichidant-R, a Bonanza Bros. spinoff, is the sequel to Tant-R, seen on the Sega Classics Collection. A multiplayer puzzle minigame collection, Ichidant-R is sort of a precursor to Mario Party and Wario Ware.
Hajimari no Mori is a graphical text adventure from Nintendo! Let's all hope for a miracle localization for that one.
