TITLE: How to help repay brother?
POST: So my older brother is going to college and he isn't necessarily nice (he's pretty mean and doesn't talk much). He surprised me today by giving me 3 Xbox One games. However, 2 of these games are almost brand new and one is brand new. They are all popular and expensive games and I want to repay him but I don't play Xbox One anymore. I'm still grateful but should I sell them and profit about $150 (I'm only 13 so a lot of money) or should I keep it for sentimental value? I know it sounds bad for me wanting to sell but he's been rude, disrespectful and even abusive once so I don't know what to do. Also should I give it back? Is it the right thing to do?
TL;DR: 
My rude brother is going to college and he gave me some expensive games that won't give me much value in enjoyment. Should I keep, sell, or give back to him? Should I keep and repay in some way?
