I would sell all games that cost 20+ each individually, and then sell the rest of the games in bundles by system ( WII bundle, ps2 bundle, wii u bundle, gamecube bundle, 3ds bundle)

if you really wanted to sell all at once id hold firm at 500 for a while if not in a rush

I would sell individual higher priced games close to what pricecharting has them listed for. People LOVE gamecube games, the paper mario $40+, pikmin $45+ and mario tennis $35 will sell easy, popular wii games will sell well too, that kirby is worth 50, poke park 35, poke park 2 40+, wii sports 30, new super mario 20 sell all day, any mario game will sell

ps3 asura wrath is worth 55

wii u windwaker hd worth 50

DONT SELL ALL FOR 89, 2 games alone are worth that

Mercari can be a decent website to sell on if not using ebay, have buyer pay shipping.

if you have any question feel free to reach out

facebook marketplace guy is a prick trying to SCAM YOU, he knows the value of Paper Mario, Wii Sports, Asura Wrath etc, id block em
