@Centurio Nixalsverdrus (great name by the way ):

Don't confuse the trivial script with the EBBS campaign script.

The Trivial Script is - as LordBula explained - simply a program which makes it easier to configure EB to your liking, it has no disadvantages or any impact on your actual gameplay (only graphical changes if you'd decide to install one of the Trivial Script's included optional addons).

E.g. if you wanted to play without videos, with movie-cam and in windowed mode you formerly had to edit the shortcut and put in several commands (-ne -nm -movie_cam)

Now you can just start up directly the Trivial Script and change all the settings to your liking in a comfortable GUI being sure not to mess up anything and have it all nice and clean an no chance of messing everything up ;)
