Art is a strange thing. It's not quite a product, even if we often treat it as such. It's not so customizable. Don't like your toaster? Someone is making a similar one, but with that feature you want, and it doesn't spontaneously ignite quite as often. But have you ever tried getting the museums to just do some minor fixing? They keep hanging up on me. For starters, that smile, it's just... creepy. Just get some art students and some fine brushes and fix that up. We'd all like it a lot more.
And of course, dinosaurs.
Games are art-like in this way. I won't go into the artistic merit of them, but they share this quality, of your great change absolutely ruins it for someone else. Maybe the Mona Lisa really could use more dinosaurs and less smile. Maybe it would be a much better painting. Or maybe not. Or maybe!
Just think: Dinosaurs in the background rampaging toward Miss Lisa.
Why does she have that grin? Because just out of the frame she's holding a remote detonator. Those dinosaurs aren't rampaging, they're running-to-deathing.
See how much meaning and nuance, how much drama and action is added with the dinosaurs? She's ten times as awesome, at least. Who knew she was actually a talented engineer, putting all those Renaissance men to shame? And most of the next few centuries as well. Da Vinci thought his tank was so great, but why didn't he make it? It would have been great against the dinosaurs! But she had anti-tank weapons, even before he made it. That's planning ahead. In the arms race she had stolen the starting gun and was using it to threaten everyone else.
Did you know there were dinosaurs in Italy so recently? Well not anymore, and now we know why.
Surprisingly, the dinosaurs are off-topic and now I just don't care. Because dinosaurs would have been awesome.
