In my games are 18 areas, or rather 14 game states (some areas unlock at same time). Breeding game - you have a farm, catch new monsters in new areas, more powerful in later game areas. you can upgrade your farm and each building on it (field, bed, oven, training station) seperately, each up to level 20. There are gonna be resources like wood and stone, but also late game resources (maybe about one-two resources per area). When player finishes he should be level 80, he starts level 1. Add a good economic feature (money, price, pricewalls) so the game keeps progressing in a not too fast way, wherre you need to grind a little every where and cant just rush. Gain money by selling breeded animals or produce of animals. what i dont want: player to be level 40 when endgame, or player level 80 in area 10.
