2. Crew Mini-Games
Rockstar have already confirmed that GTAV is getting MP3's crew support, so no doubt there will be an emphasis on being with your crew. How deep it runs, however, we will have to discover when the game is finally released. As for this wishlist, a territory system could be cool for free mode: when representing your crew, fighting over a key spot like a police station or mansion earns you the right to be dominant force in the area. That territorial claim would mean that entering the location would give the player bonuses like nicer cars, better weapons and more ammo, and similarly there should be a big XP reward for taking over rival territory, so the fight can keep going. Basically like a more complex version of capture the flag. Also on the topic of crews, the safehouses would act as hangout for your crew. Having a full monetary system on top of the XP system could work, to allow the player to buy houses for their crew as a hangout in order to store guns and cars in the garage. It is a system that would mean it could be useful for higher level players to donate items to n00bs. Players should also be able to store things just for themselves.
