I've mentioned this somewhere before but truly believe that one of the main reasons for the poor sales to be the fact that there is very little supply of it at retail. I know for sure I've been shopping and looking at game stores for deals and walking down video games sections in the store and I can't honestly remember seeing Spore Wars at all. Even checking online right now at places like Amazon shows that amazon itself doesn't even sell it, its only available from "3 other sellers" all of them for around 54+shipping which is insane considering even things like SMG went for 49.99.
“When I was 5 years old, my mom always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down “happy.” They told me I didn’t understand the assignment and I told them they didn’t understand life." - author unknown
