Hi, first time post, joined just because I was getting frustrated at seeing everyone miss the obvious term for the gaming equivalent of a blockbuster.
It's called a System Seller, everyone. They're games that are so good, so desired by people, that they'll go and buy the system for that specific game. Few games truly achieve system-seller status.
Anyway, those walls of shame are quite revealing. I only wish it were possible to get budget data, so that you could re-generate the walls from the developer/publisher perspective, and see how much money would be saved by cutting out all the shovelware, and how much would be able to be fed into the decent games to make them great games. Heck, there are some games that could have been system sellers, if they'd been given the appropriate budget.
