It's a fun, if somewhat standard breeding game. The premise is that you inherit the ranch which is severely in debt, and you have to breed monsters in order to pay off that debt. You can play as a male or female, and you can try and breed the monsters yourself, but most monsters have a better fertility rate than the MC. So it does behoove you to try and get male and female versions of most species. Be aware though, that some(most?) are locked by sex(i.e. catgirls are female, dickwolves are male) and requires inheriting a specific attribute to unlock the opposite sex of a sex locked species. It can be very grindy, as you will initially try to get/breed species with good good attributes, until you have 1 or 2 of a species that has most of the desired attributes that you can then use to propagate monsters for turning in quests. Most species can reproduce across species(again, catgirls and dickwolves) the resulting offspring is usually limited to the species of the parents. There is a wiki available that was pretty up to date at the time the game was abandoned if you want to know anything in particular. There are some character related quests, although they are somewhat limited. Overall though, I enjoyed playing the game, and if you enjoy a monster breeding simulator, perhaps you will as well.
