I'm reasonably sure none of what you write in this post would be different if you deleted the words "expressing ourselves through" in the first sentence. Nevertheless, I think it might be worthwhile to think about why you chose to couch your enjoyment of video games in the language of "self-expression" and what, if anything, you mean by that. Is it just a prestige-grab for an activity that is more properly classed as entertainment? In any case, it's an implicit claim of worthwhileness for video games that I would encourage you to make much more explicit in your own thinking in order to see if you still agree with it -- at the very least by tabooing "self-expression" and similar terms.
