I can't wait for side activities.
I remember back in the GTA 3 days you could steal a taxi and take people to where they needed to be to earn money. They haven't confirmed what's in the cell phone and what apps they'll have but I feel like it's almost certain we'll be able to do Uber or Uber Eats. I just want to do food delivery and spit in someone's onion rings or beat their ass for not tipping. I also hope they modernize the dating from GTA 4 and have a Tinder equivalent where you can set up a profile.
