Playing Age of Empires 2, Definitive edition, which is really fun.
A graphically updated and QOL update to the very old strategy, kingdom builder wargame.
The devs reeally have put a lot of work into this.
Sometimes I just like to spectate games and watch people's strategies.
Usually I play SO vs AI, playing various scenarios, quick maps and so on.
It's really cheap too, so great value for money.
Been trying out/going back to other games that I've had for a while such as Stellaris, Witcher 3 and so on with various levels of interest.
