My favorites are Minecraft and dota. I could play both for hours when I was a kid. To be completely honest, I had some adult games in my hidden folders xD. I don’t have a lot of free time now because of the huge workload. However, I do sometimes indulge in some minecraft.buzz action. I started with the single-player mode and then moved online. My first days on the server were pretty funny. I’d goof around with the chat and the mods. Ah, good times… 

My favorite has always been Crysis and Far Cry. These two are games of my childhood, and I’ve spent most of my time playing them.
Now I play way less, but I still follow https://zumroad.com/game to keep track of all the events in the gaming world. It’s interesting and helps me feel I don’t miss so much. Keeping track of all the new games is a way to have a topic to talk about with some of my gamer friends. And who knows, maybe one day I will buy a gaming computer and start everything from the beginning. But I would need much more free time for this.
