AITA For refusing to loan a $200 game back that I specifically told her I was keeping for myself from now on?

A couple of months ago I loaned a game to a friend. I no longer play it so I thought it wouldn't hurt if I loaned it out. It was actually a brand new copy of the game that I never even opened. Recently, I decided I wanted to play the game just for old times sake. So I messaged my friend and said I wanted it back. This turned into an argument. She offered to give me money for a new copy, but I said no I just want my physical copy back. She said why can't I just buy another copy and leave her alone. This back and forth went on and on with her giving me low offers of money to just by a new copy (I am assuming she did this to be respectful, not because she's cheap. She's not cheap) and me refusing. I said I don't want a new copy I just want my original copy back. I told her there were achievements in the game that definitely would not be achievable for me anymore now that I'm older, and that there was a specific character that I had leveled up and I don't want to lose him by getting a new copy. It isn't a big deal, but I still want my stuff back so I can just have it. I haven't gotten the game back yet, so I am planning on just going over there tomorrow to get it back.
