Secondhand store if you just want a safe place to get it over with and don't care about getting the most money you can for it. Craigslist if you want the most amount of money for it and can handle the awkwardness and potential danger (however unlikely) of meeting people in person. eBay if you want a medium where it's pretty safe but they do take a little cut.

If you do CL look into if your local police station has an area where you can do those transactions. Maybe I'm a little bit paranoid but I personally wouldn't go around selling hundreds or thousands of dollars of stuff in person to a stranger. An individual game here and there, sure. Aside from the safety aspect, selling as a lot will also most likely get less value than doing them individually.

Not like you have to choose only one thing. If it was me I'd probably sell the higher value games on eBay individually and then package some lower value ones together as a lot (whether it's to sell on eBay or CL).
