For me it was Terraria, Satisfactory, Tetris Effect Master Mode, Minecraft with Mekanism mod & CSGO / CS2 (almost 2000 hours in CS alone).
Edit: There are so many answers that I might only reply if I have something interesting to say. I will read all of your answers though. 🙂
Edit 2: It has become too much for me and I have to disable notifications. Thank you for the massive response and please continue to discuss with everyone here. ❤️ 🫡
I’ve easily got a full year into Minecraft since I started playing back in high school. and that’s just active hours, not afk. I’ve never joined a public server
even accounting for the second account I bought for java and the bedrock account I may have had to buy when my account didn’t port over properly, it’s still the highest time/$ game I’ve got
