We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Lots of reasons for the decline. First, the big companies bought up most of the best games and hired the programmers, and quietly killed many games that were fantastic.
The quirky geniuses couldn't handle the marketing needed to get shelf space. It is weird that they didn't just leap to selling online but that leads me to my second point: you had to pay off Bill Gates and his evil henchmen so that your game would run on their systems. Small garage developers can't play in that league. Numerous fantastic computer games came out,but their producers didn't pay the fees necessary for their games to continue to work on new computers.
Third, most Americans are too stupid to play the kind of strategy adventures that there are still a few of. They'd rather just play point and shoot with enjoy blood and gore, plus the occasional bimbo bursting out of her bodice.
I know several teenage children with genius level IQs, social misfits, who derive enormous pleasure and satisfaction from the few few computer fantasy and adventure/strategy computer and video games still left.
