Well the big deal of them is that Japan LOVES giant robots, they have loved them since the first coming of their comic books. So when Banpresto came out with the Super Robot Taisen series, they combined the robots everyone loved with a very simple system SRPG... it was a great mix. So the fans in japan loved it, then the fans in america loved it... so Banpresto continued to make it. So think of it this way, it's the only way fans of these robot series old and new can interact with them, that and they're just super fun to play to see all the neat little tricks you can do with certain teams. =DWhats the big deal about this 'Super Robot Taisen' series?
