A group of my friends often play semi-long term strategy video games together online. These games often span several play sessions a couple of times a week over a few months. Recently, one of my friends, George, commonly involved in this game has taken on a new aspect of his life that makes it very difficult for him to play consistently. We often desire to play, but since George's schedule is very firm/not accommodating, it's very rare that we get to play anymore.
As a group, we've decided that we'd like to start a new game together and would like to tell George.
However, my friends are very non-confrontational and have trouble telling him.
Normally in this situation I would take it upon myself to tell George on my own. However, due to the specifics of the dynamics of this friend group, I'm not in the best position to deliver this news.
How can I convince my friends that they need to assist me in telling George that we'll be continuing without him if they want him to be informed?
I've tried to take initiative and let him know that we'd like to start a new game, but none of my friends backed me up on my "claim" to which he just assumed that I was just joking.
I'm specifically looking for language/reasoning to effectively communicate to my non-confrontational friends that in order to achieve what they want they need to be somewhat confrontational and communicate as a group.
Additional clarififcation
Our group finds large amounts of time between play sessions to be extremely detrimental to our play experience, which is why we do not wish to continue the current game with George. To put it in perspective, a full playthrough of the game we play would normally take roughly two months. However, if we continued the game at the rate that George is able to participate it would take more than a year to complete which is unreasonable to us.
