I have two ideas about that, each one very different from the other.
The first would be an FPS RPG that would be something like a hybrid between Fallout 4 and Borderlands. It would be open world with a high degree of weapon customization. An advanced base building system would also be included. It would have great shooting mechanics and a semi-scaling system that would keep you from feeling overpowered. It would need a monster of a PC (not for graphics, I don't really care about that) so that loading screens would be tiny and there would be no fps dips. It would have plenty of quirky humor and highly customizable characters but it would also have serious elements and themes. It would have hundreds of hours of content and crazy mod support.
My other idea of a perfect game is basically Final Fantasy Tactics. I want everything that made that game awesome, just updated and refined.
