GTA Online is my most-played game according to Steam, but that time is largely skewed from how rough the game was upon its original launch. Rather than put up with nearly hour-long loading times whenever I wanted to play, I used to simply leave the game running overnight. And as a result, I’ve got a few thousand hours in that game.
Project Zomboid is a distant second according to playtime, currently around 900 hours, but I think I’m catching up to it in terms of time I’ve spent actually playing the game.
Something about sandboxes with cars and guns that just scratches a certain itch for me.
I’ve also got at least a few hundred hours on iRacing, but because I haven’t linked that to my Steam account, I don’t know the exact amount of time. And I’m not going to look back through my race history to add up every minute of virtual track time.
Project Zomboid has a tutorial, but it’s strictly optional to play. You can absolutely just dive straight in to it.
Knox County, Kentucky, 1993. The zombie apocalypse hits. As far as you know, you’re the last person alive on earth. It’s all up to you, and you alone, to keep going.
The game’s default settings are plenty brutal, but you can tweak them to an insane degree, and anything the settings don’t cover, someone’s probably made a mod for that. I highly recommend the Bandits mod, which adds hostile human NPCs in to the mix of all the things that will kill you.
