Please God - A good theme!

Here is for hoping for a great theme this time around!

There have been some good themes in the past, but also some pretty bad ones imo! Everyone is free to vote after their own will, but here is my opinion on what makes a theme good and bad. I know the theme can be used as much of little as you want and be interpreted however you want, but I still feel it's important to have good themes. Hopefully some food for thought when you're slaugthering!

What a bad theme is? * Too restrictive - shouldn't kill creativity and make all games the same * Too open/abstract - Doesn't actually say anything, might as well not have a theme * Memes/ForTehLulz - Usually not good inspirations for games. People put down a lot of energy, let's not make it for 1.5 seconds of smirking on a newsfeed * Game-mechanic or style centered - It's not fun to rate games if they are all built on the same mechanic or all look the same * A long sentence - A theme shouldn't be a light novel, one or two words to describe it should be enough to keep it open

What a good theme is? * Restrictive enough to challenge the mind in making something fun out of it * Open enough to many interpretations

Comment if you have any other good points to consider or don't agree at all :)

Anyway, happy slaugthering!
