This is kind of a weird favorite memory because I play a lot of more popular and fun games with friends, but my favorite time is when we rented Return Fire for Playstation and played that for 7 hours straight. We had this impromptu tournament between the 8 of us. We had pizza, Coke (Sprite, Mt. Dew etc.), Cheetos, and Popeyes chicken and biscuits. And that was like 7 years ago and I haven't really had such a memorable time playing games since then. Not even long hours fighting games and RPGs match that kind of intensity. We usually got bored of games really quickly and watched movies instead. Only long nights of AD&D (Forgotten Realms 2nd Edition!!!) and Shadowrun could match the fun we had.
