One thing that definitely improved tenfold since GTA 4 is police chases. Now that you don't need to get out of the search zone, it's a much more interesting game of hiding rather than running.
Amen.
I was so hyped when I noticed that you actually CAN hide behind some structures and they won't spot you, even passing by - no AI cheating.
Overall, Police AI has improved dramatically. Up from 3 Stars it becomes really tricky to survive/lose them. Especially helicopters. 4 stars is already barely survival. Never managed the 5th star but I sure keep working on it.
Main reason for a free roam rampage being entertaining and fun.
I hear rumours about Casino DLC. Also you can create a Server where only your friends can join or Crew only or Invite only. Yesterday I mostly stick with my friends rather than random people ( I generally get KOSd )
We should try a private crew server at some point and wreck havoc with 5+ people
How many players are Heists? Is it always a 4 man crew?
Maybe we can use some TS server and do some heists.
