Have you ever thought, "I love Minecraft and Terraria for their clever title screens?" Well you can be clever, too! Edit your random slogans into the script and it will pop up underneath your game title on the title screen and beside it at the top of the window.
How to install: Drop the file into your game folder > js > plugins. Open it in your game's plugin manager, and change the texts in the parameters. It allows for twelve different slogans, and if you only want one you can paste the same text into all of them. Or, you can edit the script to suit your needs as it's pretty short and simple.
Edited on 10/27: The first release didn't use parameters and simply asked you to change the quotes in the file.
