No it wasn't... It scored and sold very well.
I've never played a boxart before, maybe thats where you are going wrong! =)
It had a good start, but never broke 300k in lifetime sales. Not very good at all considering some Xbox 360 exclusives have beat it going on Japanese sales only. It also scored roughly 7s and 6s, so it is Iron Man DS quality.
If SEGA never had anything to do with the project, you would have never gave a shit to begin with. Have you played it? Well I have, it sucks. Sands of Destruction is way better in practically every way, and I did not even like that much either.
7th Dragon sucks, the extra proof is that it is one of the most requested games at the SEGA.com forums. End of discussion. Let's get back to Force! I never played it! Is it good? I bet its good!
