Game franchise crossovers seem to be all the rage these days! This one is quite interesting, as it is a collaboration between SRPG series PoPoLoCrois and farming series Bokujou Monogatari (known in the West as Harvest Moon until recently).
For those unaware of PoPoLoCrois, it is a manga series about the power of love and friendship. It has also sprouted numerous SRPG game releases. The PSP release, simply titled PoPoLoCrois, is the only game in the series that has released in North America and Europe.
The aptly named PoPoLoCrois Bokujou Monogatari, or "PoPoLoCrois Farm Story," will feature a command-based battle system and farming elements such as raising animals and crops. It will also feature characters from the PoPoLoCrois series.
PoPoLoCrois Bokujou Monogatari will be available for 3DS. No release date or plans for localization have been announced yet.
