Portal and Portal 2 are some of my all-time favorite games. They’re about the only games I enjoy watching other people play, primarily when they’re playing for the first time—it kind of lets me relive that wonder of the first play through. Going through those with my stepdaughter (only 10 at the time) not long after I married her mom was a highlight of my life and really helped us form our own bond. As we progressed through I realized that chamber 17 was going to be rather traumatic for her because she was going to absolutely love the weighted companion cube, so we stopped playing for a few days while I ordered a stuffed weighted companion cube and gave it to her right after the level. As we neared the end of the game I explained to my wife about the Cake. She owned a bakery at the time and we presented kiddo with a cake like the one seen at the end of the game when she won. We did Portal 2 as well, me watching as she played the solo campaign and then we did the co-op together. I’d highly recommend it for any parent who likes gaming to share these with your kids.
