About a year ago I found Stubbs the Zombie for the OG Xbox in mint condition for about 5 bucks. It ebays for much more and surprise surprise - it's a great game to boot.

I also picked up Kinect Sports Rivals for 10 bucks and it's a great game too!

I found the whole NEC Supergrafx (only) game library (5 games!) at a used store for 100 yen each (just under a $1 USD each). Hucard games only (no box/manual), but still nice. Sold 1941 for about $200, Aldynes for just under $100, and sold Daimakaimura (Ghouls’n Ghosts]) for just under $50.

Included the other two common/cheaper games with my Supergrafx system when I sold it off. I wasn’t really using it (wasn’t RGB modded) and I wasn’t really into the five exclusive games besides GnG. Not worth keeping a system around for though. Still have my RGB modded Turbo Duo-R for standard PC Engine Hucard/CD games.

Got the mass effect trilogy for 5 bucks a few years back. Best purchase ever...

Driveclub for 3€ and NHL 17 for 4€ were pretty good, I think.

Orphan Scoin of Sorcery on PS2.

The game was horrible...but for some reason I liked it. Do not know why or how, but I played it over and over several times. Best waste of 10 bucks I ever had.

Well, I managed to get Mega Man X3 for 16 USDs about, granted it's the Japanese version. Still, that price beats around 200 at the least.

No Man's Sky for $5 at Wal Mart. The game isnt anywhere near as bad as people make it out to be.

If you got it for $5 at walmart, chances are you got it way after release and are playing a totally different game than what was released.

yeah got it around Oct 2017, while the game could probably still use some work...it was a steal for $5 

I was able to borrow a lot of Wii U games so I didn't really have to pay for them to play basically all the titles on the Wii U
