Maybe the title of the post is right - the Wii is selling highly above than its competitors in Japan, North America, UK, France and Germany, which are the world's most important console markets. If the Wii cannot perform that well in Spain or Italy, then it can be viewed as a "failure", especially when we consider that the Wii was released in December 2006 at €250 and the PS3 was released in March 2007 at €600...
Anyway, Portugal's sales are included in the Spain figures? In that case, shouldn't the data say "Spain and Portugal"? Also, why not separate them? Or the figures are supplied to VGChartz added up? Most important point here is: if Portugal is included in those numbers, then there's no way that the Wii will outperform the PS3 in terms of commercial success.
I'm from Portugal and here games = PlayStation; this is Sonyland for the last 10 years, the PS1 was a smash, the PS2 was even bigger and according to Sony Portugal, the PS3 is performing even better than the PS2, a few months ago they claimed to have sold 40 000 PS3, against about 30 000 Wii and 15 000 XBox 360. By the Way, the PS2 numbers were at about 750 000, and if the PS3 is indeed selling at a higher rate...well, you can see where it goes.
The PlayStation brand is so embedded in the minds of the portuguese consumers that everyone uses the word "playstation" meaning "games machine", if a person goes to a shop to buy their kid a games machine, they will most likely buy one of the PlayStation brand (because the sales clerk will recommend either a PS2, a PSP or a PS3), the top selling game is ALWAYS the latest version of Pro Evolution Soccer and except for a few thousands of people, it's impossible to talk about a games' subculture here.
Naturally, most people buy crappy games without knowing what they're buying - but then again that doesn't really affect them because they have no criteria or any level for evaluating their purchases - for the average portuguese consumer, a game is good if it has portuguese football teams. And Nintendo is "for kids" - this is an unavoidable statement in Portugal, usually said by kids who are between 10 and 16 - Mario is "for kids", Zelda is "for kids", Metroid is "for kids", Wii is "for kids", DS is "for kids".
I'm an exception - I have all the Nintendo consoles that were released here, plus an american SNES and I do some import gaming - this means that not only I have access to a much better offer than what is seen in the portuguese shops, but I also pay much better prices than the shark-like prices that one can find in this country - most GBA games still cost around €50 in portuguese shops, and if you are lucky enough to find any GameCube titles (difficult, because the GC was discontinued in Portugal in about 2004), they still cost €60, even if they're from 2002.
