I enjoyed the rant, but I always find that threads like this turn into one giant jerk circle. We already know that games arent worthless, that theyre an exciting new medium etc etc. You're pretty much preaching to the choir.
You have pointed out a problem i've been seeing. While youd have no trouble on this site reccommending interesting , innovative, even odd games, or having a real discussion about whether or not games are art (even if that generally is just people saying "all games are art" without any real qualifier). But in real life it's a lot harder. My Sister, for example, seems to exclusively play casual games on her phone. Shes vey much into one in particular, a slot game with all the fun of playing slots without the monetary aspect, which really irks me. Anyhow, she mentioned the ad for Portal 2, and said it was funny. I mentioned I had it, told her it was a pretty good game, and said she should try it, to which she responded "nah it seems stupid". I felt such an urge to smack a *****.
But even though I call it a problem, it isnt really so. I look at all the frat boys playing Black Ops, the annoying highschool girls playing Farmville, the housewives with their Bejeweled and Peggle, and see the same escapism quality that made the film industry grow to acceptance during the Great Depression.
Now, I know you dont really want to think that these are the games that are going to bring video games into general acceptance as a real medium, but you have to accept something ive learned long ago. That the best of anything will never be the most popular, at least not while its new. Look at the film industry, or even the music industry. Chart toppers are merely passing fads, while the truly great entries dont even grace the top 10. Give it 20 years. Noones going to remember Black Ops, like noone remembers the Highlander sequels, or how noone would listen to "Sugar Sugar" unless they were being ironic.
I really liked the rant, but id urge you to post it where other people can see it, not just gamers, everyone. I saw its been posted on what I can only assume is your tumblr, so thats a good start, but who really reads a blog anyway? Try get it published in your University Newspaper or something.
