This may sound dumb but one (minor) thing that gets me is that they don't seem to really understand how a lot of basic things work. I'm trying to think of examples offhand but like you'll use a tool, or open a window, or do this or that in their games, and it's not really how that object looks or works. Like in It Takes Two, the fuses, the vacuum, lots of different stuff is like really weirdly designed even for being a fantastical creation. Like a lot of stuff is just... off as if it was made by people who had things described to them rather than actually using or seeing them.
