I have starting this gen. I'll probably end up selling the ones I know I'll never play again though like Assassin's Creed Unity.

Always keep them because it's pitiful what you can sell them for. But really, I doubt I'll ever play them again.

I keep some and I sell others.

I always buy games when they are at their best value and never sell them regardless.

I dont see the point in buying a game at release if it will be half its price in a few months.

no, i will try to get rid of everything either sell them or give away when i'm not playing them anymore...

This is what I'll do too most likely. Sell the garbage, keep the treasures. I want to get a nice stack though. 

FOREVER AND EVER. BACK TOGETHER. FUCK.

That's why i prefer physical copies more then soft copies , YES i keep them in my private bunker

I keep the ones i really like and the ones i think i would replay sometime (so, also really good).

The rest i sell, especially if after playing the game i say with full confidance that i will never play it again.

I keep everything, and I always have since I was just a child. Even those that I didn't like or won't play anymore. It's nice to look upon a box of some game and think "kolere wat een schijt-spel was dat ook echt".
