I'm doing a project management (software design - games) class, with a group project that goes a few months. One guy in the group who has an important role keeps ignoring the documentation we produce, makes his own conflicting documentation for the same thing (without reading the existing file in the same share folder), and then makes a third version of the final asset which contradicts both his and my versions of the app-flowchart, and has additional undocumented features that he just thought up on the spot, and would require us to generate a whole pile of assets we never planned for.
The guy's a total dickwad and I would never hire him, he's the type of guy that rejects everyone elses ideas in a smug way, yet he can't do shit himself. Pretty much I mention some game idea and he's constantly yelling that it would never work, yet they're usually ideas that are making a ton of money in the real world. So because they're not the exact game he would buy, he rejects the idea that anyone else might like it. And it's not like a discussion, it's literally you say "a game with dwarves mining into the earth might be fun" and he's screaming how it's a terrible idea within two seconds and won't let you get another word in.
He's the most stuck in his ways guy I've ever met who wants to be a game designer. Totally blinkered vision and no imagination / seeing outside the box. He's the kind of person who hears you say something he hadn't heard before and tries to shut you down: "no no no that can't be true your wrong" and you have to google it to show him it's real. I had this happen 4 times in 10 minutes in the first team meeting. People who have zero imagination and zero ability to process new ideas are really tiring to talk to. Hell the guys not even any good at coding or art. So he sucks at art, coding and game design, doesn't get the "team player" thing, and is an annoying argumentative person. A great catch for any future game company.
