I do agree with you that ultimately it would be nice to keep all the games you buy in case you want to replay them in the future but I often play games repeatedly for months, sometimes going through all the levels of difficulty as well as trying to complete all the trophies & other achievements.
In the end I tend to get bored of them after doing what I perceive as everything plus I don't like paying full price (£39.99-£49.99+) for games that have just come out so it's nice to put used games towards new ones.
Traded in "Fallout 4, Dirt Rally and Sniper Elite 4" towards "Sniper: Ghost Warrior 3" the other day which was £49.99, of which I paid £6.99 on top of the games I traded in so not bad I thought.
Yep I like having something physical that I can touch. "Oooohh erhhh Mrs"
I've got Snap-On, Halfords Professional, Bluepoint (Snap-On again but cheaper), DeWalt and some miscellaneous tools but decided to try Teng Tools when I needed a mini ratchet for working at a new job.
It's a great bit of kit, very strong, compact and with a lifetime guarantee I'm not worried about breaking it.
Not cheap but quality never is. Highly recommend it.
