In general would only play single player games, unless maybe if it was a fighting game, but even then I would rather play them locally instead of online. But more importantly I'm looking into games that support Mods and Customized Made Content from their respective communities, and many PC games support this and have the possibilities.
I'm itching for Fallout Primal. The historical origins of mankind are so rarely explored in games. If they are explored in games they are usually reduced to portraying us as stereotypical cave men wielding poorly made clubs and spears. But you can see in the game that there's more to it that that. There's an actual stealth system in the game, you can weild clubs, spears and arrows that have very intricate designs that go beyond just wood bulb or a stick with a pointy rock at the end.
The next Assassins Creed game. Awesome game series and I even learnt more about the french revolution and the industrial revolution than from my history teacher. Thank you Ubisoft allowing me to skip class, enjoying my game and passing my tests.
