My ideas are here. (0.2)
1. Make you own character just like in gta 5. If its impossible make it like gta 4 online
2. Make gamemodes.
3. Make a gamemode where there is no godmode or anything just like gta 5 online no one has any special powers or anything.7
4. Focus on fixing the damage we put on to a player. It takes a long time to kill somebody
