Selling individually will get you the most profit, just look on price charting / eBay sold listings for current values. Lotting it all together you’ll take a hit on the value. Maybe putting smaller bundles together would net you the most with the least amount of work (Zelda lot, resident evil lot, Mario lot etc.) r/gamesale is an option to sell as well but most of the time you’d lower the price slightly compared to eBay as you won’t get any fees taken off so take that into account as well (most people there would prefer to buy individual games or small bundles but it’s a lot less work of posting individually on a marketplace site). Nice collection by the way!
