there should be item system, random item are droped from monster, like potions, armor , rings, weapons.they should boost stats. AI should be able to choose the best one and sell others to market , then buy good one later with the gold that the AI won. When inventory is full,the ai should return to the city to sell, sleep and buy item. its a big . but a great inprovement that could be added to game.
