I took some time away from the game after I was given billions of dollars during the hacking/cheating era. I picked it back up now that the money and cheating is mostly gone...and I am very pleasantly surprised to see a completely different community now. I actually hung out with several randoms that didn't shoot me on sight. This rarely happened before in free roam.
The biggest reason I quit awhile back was because NOBODY played deathmatches, races, and co-ops. Everyone was rich and had everything, so hardly anyone played the missions. This HAS CHANGED. In the last 2 days, I have hosted a LOT of co-ops. The room filled up with 4 people almost every single time. I have chosen to join a random co-op over 20 times, and each and every time I was put into a full room or almost full room.
This is something that I rarely came across before. Most of my night was spent hosting, inviting, waiting, back out...try another session, host game/join game, sit in empty lobby again for 10 minutes..give up and quit. That was an average night of trying to do missions. Now, on PS3 at least, I always see 16 player sessions, full mission lobbies, and players actually playing together.
Rockstar really gave the co-operative community a boost when they took the money and hacking away. Nobody can afford to just spend hours griefing in free roam anymore. Great move by Rockstar. It's been a very obvious plus for me and lots of others who were really missing that co-op community feeling in GTAO.
Now I just can't wait for the mission creator. From the video I watched on the mission creator, we will be able to create some true stealth missions. This game is sorely missing a reason to care about your stealth skill, but that will soon change when the mission creator is introduced in the content creator soon.
