Bethesda's Creation Club, which sells small pieces of content created by paid modders, hasn't received an entirely warm welcome from the Fallout 4 community. Among other concerns and complaints, there's the fact that since updating to version 1.10.20, a rather large and unsubtle advertisement for the Creation Club now appears in the upper right corner of the main menu. Well, leave it to a modder to figure out a way to remove it.

The mod, created by 'InAComaDial999', is called No More Creation Club News, and it's currently the second most voted-for mod this month on Nexus Mods' Fallout 4 page. Once installed, you won't need to see the Creation Club announcement (and the offer of 100 credits to use in the store) every time you start the game. I suppose you can read it as an objection to the Club itself, or as a simple desire to remove an unwanted element from the menu. Either way, it's what mods are for: to tailor a game in a way that suits you.
