Been playing for at least 30 hours now, and I've never seen a repeat, always get new ones. Seems like an absurd amount.

@krullban: I believe the scientific term for it is a "shitload" of character transitions.

I've seen Michael repeat pretty often. He's been sitting on the hood of his car smoking a cigarette multiple times, as well as a park bench. Franklin's walked out of the strip club at least 6 times.

I've had Franklin and Lamar fight to cops or gangmembers loads of times and Micheal just sitting around. But been messing around alot with buying stocks on all three before doing a mission so lots of switching.
Trevor seems the have the most diverse and fun ones, no repeats on him yet!

There are a TON. I've had a few repeat, but nothing major. I've been told about alot more that i havent seen.

There's a reason the game cost so much. They filled it with as much voice acting and animation as possible.

That said, I've had them wake up in bed multiple times but that one is OK to repeat.
