Earlier this year when I joined the XBox crowd, my trade-in experience was pretty similar but really only based around the PS4. I traded in my PS4, 6-8 games, and 2 controllers. There was a trade-in promotion, and I ended up walking out with the Battlefield XBox One S bundle, FIFA 17, a 12-month XBox Live membership, and an extra XBox One controller for like $30-40.
Gamestop has GREAT deals if you're patient enough to look for them. I picked up a new copy of Injustice 2 this past weekend for $39.99. It was even cheaper than the sale price on the XBox Store ($44.99).
