There's only one game that pops into my head for aim assist and that is GTA. The only game that I've seen that when you aim you don't have to use the analog sticks for it to lock on to your opponents.
Only online pvp game i have ever played aside from destiny was Halo 2. I think i was about 24, maybe 23 so this is a long time ago. 10, 12 years ago? I can't remember.
Anyway that shit was really fun. I don't think there was aim assist and everyone had the same guns so no one would bitch and complain. I had a blast
