Congrats you've won....no need to play anymore I guess.
I honestly think this is the exact reason so many of the glitchers/hackers/friends of glitchers bitch so much about the game and R*. They've glitched their bank accounts full and bought everything they want so in their minds they think there's no reason to do anything else in the game (fun? whats that?) that after spending hours in front of LSC that they just don't know what to do with their time online anyone more but troll people with their tanks/Entitys and endless bounties/mercenaries/muggers. It seriously seems like from the point of view of a large amount of this group of people that money is the only reason for doing any of the activities online, everything from random events, to jobs and missions, and the only things left to do are things that involve spending that money.
Honestly if someone's only enjoyment from GTAO comes from buying everything - they really should not waste their time at all and go buy another game. You should never buy games just to finish a checklist - you buy them for FUN.
RP provides your progress/levelling - not cash - you can buy cash in the game store.
I eventually gave in and glitched, I bought everything I wanted, now instead of grinding or hunting out high payout jobs, I'm free to play the game. Anything from hanging with crew members in free roam, to high level missions - I'm in!
So while some players are just repeating Coveted or Survivals I'm out there playing every single part of the game and loving it.
