I have been wondering this for some time now. I can decide whether Air Control (http://store.steampowered.com/app/295810/) is a parody game or not. If you don't know the game, I strongly recommend watching a video on youtube about it. The main premise of the game is that is it a flight simulator.
However, the game is terrible in so many ways, its hard to pick the worse parts of the game, but an example would be the menu's don't disappear in game, and the curser isn't locked to the middle instead the developer has buttons on the screen (whilst you are playering) to centre the cursor to the middle.
The reason I think it may be a parody is that I have seen all of these terrible features in other fully released games, and it seems the developer has compiled them all into one game. Another thought that it may be a publisher that made a game using the worse bits from all the games that come across his desk. However, it doesn't claim to be a parody game, and has received A LOT of flak for being so bad. This could just be some un-experienced person that got lucky with a publisher and BAM its on steam.
I'm still undecided, what do you think?
