It's a well put together musou game that definitely grabs your interest in the Dragon Quest series. It has an emphasis on tower defense, so if that's not your thing I would suggest staying away.
The core gameplay is a big improvement over the first, while retaining the strange jank and bizarre storyline that made the first game so charming. Plus Francis York Morgan is just so much fun to be around and hear talk.
It's a good game, the combat is top notch, but the story writing is just about above a webcomic in quality. It has a lot of promise, and I hope that Future Club manages to make something akin to this, but improved of course.
