i haven't been to many, actually. i worked a few at gamestop when i was there, though. i worked the destiny release, one of the madden games (no one came and i got to leave early lol), and a call of duty but idr which. i've been to midnight releases for smash 4/oras and twilight princess hd, as far as i remember. despite the fact i haven't been to many though, they're usually fun! all the ones i went to were also at the gamestop i worked at and it was always cool. we had pizza at one of them and we had a smash tournament for smash 4's. there was a trivia game w prizes for the twilight princess one. that one was a big deal too bc originally we weren't going to have one, but our manager said if we got a certain amount of preorders for it, he would talk to his manager about allowing us to have one and we actually pulled it off.
unfortunately, i feel like they're turning into a dying medium unless it's a big released like smash. most people would rather not deal with the lines and just download the game right at midnight than be out somewhere and have to drive back home. i haven't been to any midnight releases since moving so idk if anywhere around here even still does them lol.
