I had shrinkwrapped someplace, one of the Apple II Origin games, it was Ultima IV I think (could have been V or maybe it was Moebius)...
Regardless, price tag was $60. Games have always been expensive, just the way it is.
You can wait for sales, used prices or even video game crashes. I vaguely remember Atari 2600 games from $1-5 at various stores.
Support the community is what I say, I bought both L4D and Deep Space new full price and wasn't let down. But then again I have bought a lot of shit games at full price too.
One thing I'm not supporting anymore though is PC gaming, I think I'm done with that. If I was to buy PC I hate to say it but it would be Steam. As much as I don't like the whole online validation whatever krap, I don't like all the installation of all the extra DRM you get from all the disc titles.
