I wouldn't be surprised if Radiant Silvergun got more sales considering that it actually GOT promotion unlike Guwange and the rest, in which case I'd find it a stretch to blame Guwange's poor sales purely from being a shmup.
Guwange DID get promoted. It was advertised on the front of the dash for a week (the week it came out).
Maybe in America or Japan or whereever the hell you
live but not here, and I would've noticed it because I was up to see it get added to XBLA, so the promotion on the dashboard can'tve been worldwide. I said as much in the Guwange XBLA thread at the time, it just popped up in the games list obscurely like all the other miscellaneous XBLA titles. Radiant Silvergun on the other hand got a spot on the Dashboard even here.
As for proof that Guwange bombed, imagine a  tag next to all mentions because I haven't seen any besides remembering some posts bcass or someone made which had links and/or "oh it obviously failed". I personally haven't seen much to prove it other than Good Game not covering it (which I thought strange at the time before I realised that contrary to their words for the Megadrive and Zork-likes they were pathetic CoD fans).
The only proof I've seen is that it appeared in the weekly major nelson top 10 for a week, then completely disappeared. Not a good indicator of good sales IMO. If it had sold well, I think we'd have seen Dangun by now.[/quote]
This makes sense. Since I mentioned it, how long did Radiant Silvergun last on "the weekly major nelson top 10"? If there's a distinct different one could definitely rule out arguments such as "oh it had poor sales because it was a shmup and shmups are niche".

It all makes sense now: all this time North Korea has been terrorizing and starving its own people in an effort to lower the rank.
