Recently started playing Portal for myself. I've watched two people play it from start to finish, but I haven't finished it myself.
Made me remember how much I love GLaDOS.
I also recently joined a multi-fandom roleplay dedicated to making you get to know characters that you're going to cosplay. The only one on my list that I found interesting was everybody's favourite sadistic computer. But a stationary computer can't move, so I gave her a mobile android body. :3
