It's always weird to see series with such high pedigree like SMT, Persona, Etrian Odyssey and Yakuza with such low sales overall. Well, at least Persona and Yakuza have a chance of breaking out of their niche space...

Way, football manager only has 18.1m over it's 13/14 games? I would have guessed they sold around 2m on average, not less than 1.5. This also includes the psp and "touch" games? I thought it was a much more popular series.

Etrian is also lower than I expected an average of 190k per "edition". Would have guessed closer to 300k.

Man Persona deserves so much more sales than it has.... Its not really a hidden gem (feel like people know of it), but its something so few choose to experiance...

Crazy that Persona + SMT is only 22m.

Etrian numbers hurt too abit... even though there I didnt expect much.

800 million? That has to be a typo of 80 million.

Are they counting the free iOS/android Sonic games? They do say units / downloads, after all.

Wow, that's a lot of Sonic

I would have bet that EO numbers were twice that. Geez.

800..

Seems they’re really liberal in what they’re counting.

Yeah most of that is free phone apps
