Could someone explain what this trend even shows, other than making a cool looking curve? It seems to be a layer of abstraction over the graph in the blog (showing the indie explosion), but which adds nothing of value.
doesn't this imply that shovelware is actually taking away some of the sales? In other words, making a large number of low-effort shovelware is a better money making scheme than making 1 (or few) mediumly good game?
