Not the summer sale but the Steam fest, I played House Flipper 2 demo, I really enjoyed it and it turned out it was the most played one.
House Flipper is a sort of simulator, the purpose of the game is to buy houses in horrible conditions, renovate them and resell them, there’s something oddly satisfying in it, I love it :D
Microsoft Teams is the official communication tool for business where I work, no need to use whatsapp tho a few colleagues use it for fluff, as for personal/family, some of my family use whatsapp but I don’t (I use Discord), if we want to talk to each other we use “good old-fashioned” phone calls :D
