So a lot of these games have errored/incomplete data and should probably be a lot further than they are, some examples are.

Sonic the Hedgehog (needs updated euro data and.. japanese? Nearing 800k despite that)
Skate (no other data aside US yet its at 700k?)
Kameo: Elements of Power (rare said its 'near a million' and somehow vgchartz has it doing 2500 a week yet its so low, a bit over 600k)
Scene It? Lights Camera Action (over 600k but no euro data?)
Dance Dance Revolution Universe 2 (over 500k, no euro data)
Ace Combat 6: Fires of Liberation (over 500k, namco had it over 700k some time ago, it has no euro data)
Blue Dragon (the euro data hasn't been updated.. ever)
Naruto: Rise of a Ninja (no euro data)

In my opinion, all of these games sans maybe the last 4 should be over a million now or soon, but they may never reach that if the site is never updated.. It would be appreciated since people have waited a long time. For now, estimate where these games should be!

I've been really curious about Sonic Rush Adventure. Others loves the Blue Blur, and unfortunately there's no sales for that region.

With Others sales... I would say that Rush Adventure could pass 750,000 easily, maybe even reaching the big 1 million mark. Who knows for sure?

yeah I imagine any sonic game should be over a million as long as its not.. tennis.

Many, many games have either old Others sales or none at all. Burnout on PSP has had Others sales the same 2 years.
