I found a pretty good deal on Offer Up. It was 140 Genesis games for $300, which is about $2.15 a game. I got them down to 275, which is about $1.96 a game.
This is the original picture -

I knew there were some gems, but it was basically a blind buy and hope for the best. I sifted through and about 70 of them I don't have, so that's a plus.
Got them home, dumped the bag, and spent an hour digging through them.

Here are some of the highlights -

Hyperstone Heist, Lightening Force and Flintstones were a nice touch, and I've never seen a copy of Space Invaders '91 before.
All in all I'm pretty happy. I could sell all the ones I already have, at cost, and I'd still come out ahead on this one.
