And, while I can find a flaw in any console, Nintendo (who is STILL my favorite company) had flaws that made their console incapable of doing what other consoles of their generation already could.
The Wii simply can't produce the kind of AI/physics/graphics of the HD twins. The Gamecube's format made it necessary for tons and tons of dialog, audio, and even levels to be left out of some games. The Nes couldn't handle the multi-player that some Sega Master System multi-plats had. The SNES's processor caused some games to be flicker-fests! Nintendo is a phenomenal company, but (while their games are always second to none) sometimes their consoles have been a step back from what was ALREADY available on the market.
Of course, they always had advantages, too. The SNES boasted much better audio and special effects than the Genesis. The N64 couldn't compete with the CGI and audio of the PS1, but it was a graphical powerhouse. The Gameboy had a battery life that would embarrass the competition. The Wii sports innovative motion control as its standard.
I just call em like I see em.
