Prisoner's Dilemma (Need strategies)

Well, the only way you can actually win is if you defect and your opponent cooperates. Otherwise, you can never get more points than him. The game's broken.

Actually, yeah, even if you cooperate, the outcome would still be either tied or losing, so you should NEVER cooperate, ever. Broken game.

If everyone chose to only defect, then yes, anyone who cooperates would lose. But if the point of the game is to accumulate as many points as possible clearly a two-man cooperative strategy is the best. Win/Lose will not be calculated in a one-on-one type scenario, but rather the total points accumulated throughout playing everyone.
