Basketball. Same everything, except you have to dribble the ball with your forehead.
I think it would be cool if future games would focus on unique NG+ content for those who want that veteran-level challenge, and to keep it fresh (like how DS2 planted the seeds for this). Give us a few bosses that only appear in various NG+ cycles, and another super secret and difficult boss that only appears in NG+7.
Not in Elden Ring, but a few times in other games.
In DS3 I was summoned to help with Dancer, and she somehow managed to grab me and the host at the same time. So we were about 15 feet apart, me in Dancer's hand, and host floating in mid air both going through the grab animation.
There was another time in DS3 in the Cathedral of the deep. The first giant hit me and knocked me into a small corner between the short staircase on the ground floor and I was stuck there, had to bone out.
And another glitch in Cathedral where I clipped through the ceiling while riding the elevator and went out of bounds - here's a YouTube short of it that I captured and also mention the above glitch https://youtube.com/shorts/g1mHaiism_k
In DS1 I had Moonlight Butterfly glitch out. It spawned much further away from the bridge than normal, and it was rotated 90 degrees so it was facing perpendicular to what it normally would be (facing towards the arena entrance rather than facing the bridge). I forget what happened, but I think I had to save and quit out to make it reload properly.
I like Dark Souls, but it's not even my favourite Dark Souls game. Personally I think Super Mario 64 is the best game of all time, and it's not my favourite either.
