Pretty good game for its time, though certain elements did not age particularly well and a few mechanics are not fully explained in-game. Furthermore, some of the H collectibles require a stupid level of grind. Story-wise, this is where the Rance series starts to pick up. Of course, like the rest of the series, this is a fun and hilarious story. Fun game and worth playing if you're interested in experiencing Rance as a series (plus, it's free!). That being said, if you can read Japanese, the 03 remake is recommended.
