You either kill Playboy or Dwayne. You cannot reverse it once you have chosen and carried out the mission. You would have to go back to a previous saved game and do it again if you wanted to change the decision.
No, It is one of many sections where you choose in the game who lives and who dies. If you kill Playboy X and Dwayne and likes you enough.. he will send bodyguards at your request, If you kill Dwayne.. Playboy X will never want to speak to you again.
Two
call everyone again
Niko can enter Dwayne's apartment during cut scenes and a mission to kill Dwayne, but in ordinary gameplay he can only enter the actual apartment building, not the apartment itself.
By responding to Playboy X's demands that you choose between him and Dwayne, followed by Dwayne's call for you to watch out for him. The Holland Play mission will then start.
nothing happens, playboy x ignores you for the rest of the game. however reversing it and killing playboy x you obtain both his crib (giving you access to the special outfit) and Dwayne stays a friend giving you access to calling him and getting his boys to come provide you protection during missions
The benefits of Niko's friendship with Dwayne Forge (sending 2 of his goons as back-up) can be unlocked after this friendship reaches 60%. When this point has been reached, Dwayne will call Niko and tell him about the offer. Dwayne likes bowling, drinking at Club Liberty, eating out and visits to the strip club.
big smoke and Ryder
If you allowed Dwayne to live, there should be an email from Dwayne to Niko waiting to be opened, so that Niko and Dwayne can begin their friendship (Dwayne eventually rings Niko some time later). If you haven't already opened this email, it might be worth doing so to see if this starts things going again.
When you play the mission "The Holland Play", when it gives you the option to kill either Playboy X or Dwayne, kill Playboy X. After that go to an Internet cafe and send a good reply to Dwayne's friendship e-mail, then do some activities with Dwayne, wait until you get around 60%, wait for Dwaynes phone call telling you you can call back-up, and call back-up from under Dwayne's name. His goons will only last for about 15 minutes, if they don't die or you ditch them. You can re-call Dwayne to get them again after 6 GTA hours.
