you have a main character and you recruit mercenaries (you can get up to 8 mercenaries, but only at higher levels). You can name them and kick them out of your party. Some of them will retire after becoming old while others will get indepence after a level and if you choose to let him/her go he/she will send you letters and you will have a friendship.
If your main dies in a battle, game over. The game has lots of things to do and I didn't get bored with it until now. Better game I have played until now 8D
