The game did have quite a few bugs and a hilariously awful translation, but if you could look past that, it had some very interesting design ideas in it. I always tried to recommend it to mod authors, who might be able to borrow some of its ideas. Like, it had a freelancer system that was actually pretty fun and rewarding, and probably the most complex and in-depth custom troop systems I'd ever seen. Too complex to be fun, but interesting nonetheless.
It also had something very similar to Distinguished Service. That was when I first realized how cool it was to have companions who were elevated troops rather than tavern ornaments.
