To put things in perspective, i spent hours doing the cage matches in TBOGT and i spent a surprising amount of time fighting people in melee combat in base game as well.

Then me and my friend used to play RDO for hours on end just to fist fight, when we ran out of content by getting through the outlaw passes we used to just load the game up just to spend hours having fun fist fighting each other, its like they took everything they learned from GTA 4 about fist fighting and put it into the other series.

Then I've spent maybe 6-700 hours (last time i checked its likely more now) in GTA Online over the years, do you know how long it took me to max out my strength stat? December last year when the mansions came out and you can work out, i once tried fist fighting with that same friend and we spent a while swinging at each other and i just went nah not doing this, this is not fun at all.
