1. core=/=hardcore, use these terms correctly
2. Core games are supposed to be outsold. This is why they are called "core". Not made for the whole audience, just for the fans, the most demanding consumers, the tip of the iceberg.
If you want to fix this "problem", you must also fix the rules of logic.
3. stores order games based on demand. If no one buys a game, they cut the price of the remaining, unsellable game, sell it for pennies, and don't order more. If they sell out a hardcore game in two days, they will order more, and more, until it stops selling.
Hardcore games sell only for a few weeks after release, because "teh hardcoreh forum warriorz" won't find it fresh after a few weeks.
The Expanded Audience buys less fresh games, because they don't buy them with the intention of buying "the most critically acclaimed game of This Month", they buy whatever is fun for them.
4. Shovelware is a stupid term, what does it refer to anyways?
-Quality is subjective, based on preference, so if it means "low quality", Assassins Creed was "shovelware for me".
-If it refers to development costs, World of Goo is shovelware, too.
