See what fun stand-alone games I can play with this configuration.

In fact, this question is difficult for you to answer. Give you a few game names at most. I suggest you visit several large-scale game websites similar to Wanderers' Starry Sky. 2D games should be basically fine, and 3D games have nothing to worry about as long as they are not from 2007 or 2008. Recommend some of my favorite games, such as Warcraft, Command and Conquest, Red Alert, Starcraft, The History of the Three Kingdoms, Nobunaga's Wild Hope, Lehman Mad Rabbit, Need for Speed, etc. Have fun!
