The Development team behind the Mario & Luigi series have made quite a name for themselves. AlphaDream have worked on various entries to the Mario & Luigi series since the Game Boy Advance. Their works include Mario & Luigi: Superstar Saga and Mario & Luigi: Paper Jam Bros. Their Upcoming title for the 3DS is a remake+ of Mario & Luigi: Bowser’s Inside Story + Bowser Jr’s Journey.
AlphaDream’s focus has mainly been on the 3DS but it looks like they may be branching out for future projects. They have recently put up a listing, looking for a 2D/3D graphic designer. Included in the listing are the words, Nintendo Switch, Playstation 4 and Game Development for Mobile Devices.
Whether this means that AlphaDream will be branching out from Nintendo to pursuit other endeavours with other companies is yet to be seen. Perhaps they are considering other platforms for projects in the near future.
