Spider-Man 3 for the PS3, is overvalued. It sold 4,186 copies last week according to vgchartz and has sold 179,244 copies overall. This game will probably get to around 250,000 in the US, though that may be a bit optimistic. The game didn't break into the top of the charts in Germany or Spain the week of its release. (The charts the week of release have all the Spider-Man 3 sales from all consoles combined, but the next week has them by console, and the PS3 version is not to be found (but the PS2 version is), implying that it would not have been on the charts the first week if it was not for combined data).
In Britain, they have Spider-Man 3 at the top of the charts for several weeks, but that is combined sales data, which the PS2 version is probably driving most of the sales (much like the case was in Spain and Germany).
Given that Spider-Man movie tie-in games sell more in the US than they do in PAL regions, this game will likely sell around 350,000 copies over its lifetime, around 250,000 (optimistic) from the US and another 100,000 from Europe.
