Query: don't buy before checking compatibility!

Never got to play the game, as it doesn't support 90% of the video cards out there. Their site "helpfully" recommends that you buy one of the TWO OR THREE cards supported, and by the way, you'll have to kick in an extra $50 for a new 400-Watt power supply.Tech support? You can't even send them an e-mail even after registering the product. Guess you have to fork over your credit card before they're willing to have a person type back at you.Hunt around long enough on their site and you'll find a list of everything not supported (and the pathetically short list of what is). IMHO these lists should be in bold print on the front cover of the retail package.My opinion: Blatant consumer fraud.A real shame, as I really liked Myst and Exile (riven was just ok). $50 plus tax down the tubes.
