We got Chunli, Ryu, Guile and Zangief in the mix (very popular characters, been using them since the Gameboy!). Though your Sackboy may not Hadouken or Flying Bird Kick, it's still fun to go at it in your levels dressed up as your favourite Street Fighter. It will definitely raise the hype for the popular fighting game and it's a beauty to add to your collection (next to your LocoRoco!).
