Most of my favourite games are the ones I grew up with. Team fortress 2 being the top of the list.

Alien Isolation I only discovered a few years ago but always play it every October. The mechanics are so well refined and I won’t ever get sick of the ambience of the station.

VSCode. I know its owned by Microsoft but its such a good editor. Having a strong tool is so important since nobody wants to be concerned about the app, they just want to code and do their work!
