  We present an extended version of the Iterated Prisoner's Dilemma game in
which agents with limited memory receive recommendations about the unknown
opponent to decide whether to play with. Since agents can receive more than one
recommendations about the same opponent, they have to evaluate the
recommendations according to their disposition such as optimist, pessimist, or
realist. They keep their firsthand experience in their memory. Since agents
have limited memory, they have to use different forgetting strategies. Our
results show that getting recommendations not always perform better. We observe
that realist performs the best and optimist the worse.
