Perfect.
A dungeon crawler and monster breeder, you have to march up the floors of the tower, unknown how far you have to go or what's in store for you. You are human and can use your own weaponry and talents to battle but the true power that you carry is within your creatures. You take select creatures with you and level them up, evolve them, and have them protect you. You have a den in your house in which you can rest your unused creatures. You can only carry so many creatures but you can make the den bigger as you return from the tower with money and in turn store more creatures as you find eggs which you can hatch or sell.
The den is only one of many things you can upgrade. Everything in your small village is small and poor, but as you return from your countless journies with money and rare items you can afford to have more stores built along with improving your house with furniture and making it bigger. You can even build a racetrack where you can bet and make more money.
The system inside the tower is trn based. All of the creatures will move as you do and atack as you do. The maps for each level are randomised except certain set levels where preselected events will happen. On each level it is your task to train up, hunt down creatures or tems/eggs or head towards an elevator which will carry you up one level. The only escape is a Wind Crystal which you will find yourself craving and praying for non later missions. The higher you go up the more powerful creatures await, the rarer items aer stashed, the eggs to rarer and greater creatures lie in rest and the story can eventually unravel.
There is a very loose storyline. Not any set big chain of events like most games, but a general story in which you aer in some amount of control. You can choose how you interact with certain characters and choose what to put your money towards and how to treat others and act in general, this including complying with a friends request and building a fountain for her, or stealing from the resteraunt. At the top floor of the tower the plot is reveealed, but the game does not end. You can finish up there if you want or continue playing, battling your way through the higher levels and fill your village with what you will or collect all of the species of creatures for your collection and evolve all of them for more powerful partners.
Naturally enough being defeated is catastrophic, so you must be careful. All of your items, money and equipment is stolen never to be recovered and with no equipment you find yourself very vulnerable and must send in your monsters to battle until you can find moer equipment to become strong yourself again. Luckily enough, there just happens to be a store for items and money, but you cannot store them until your return so you must protect your gear in the dungeon with your life. Beter yet, you only have so much space for items so are forced to consider what to take, leave or gather up.
I don't know what i can say as a summary; perfect really. Simply brilliant, a classic that is hardly known, incredible and underappreciated. A must for collectors, RPG fans, or any shelf with games worth having.
