Whether free will exists or not would add a whole new layer to this discussion that you could easily add to almost any discussion as a wildcard. If we assume that using Windows vs Linux is predetermined as opposed to being a choice, this whole comment tree doesn't make any sense. So let's not go there.

In my opinion, if quitting playing a couple of games really is life changing to you, you have deeper problems. If your so-called friends can't understand why you quit a game over something that's more important (to you), then find different people who do. That's almost as stupid as American kids excluding other kids for not using iMessage/iPhone. Doesn't mean your friends have to stop playing these games, but you can share other moments with them. Other games, conversations, other activities altogether.
