[quote name='spmahn']That is true to an extent, but not always. They promoted Fire Emblem pretty heavily, there were plenty of ads, commercials, etc. for the DS games, and they were still a flop. In the end it just boils down to the fact that some games are not meant for US audiences, just as some games are not meant for Japanese audiences. [/QUOTE]
I don't buy that at all. You seem to be viewing the same perspective as Nintendo, which is that just having ads should be enough, nevermind the quality of the ad. I've been playing Nintendo games since around 1987, and I'm pretty sure I've never seen a single Nintendo ad that got me excited about a game. As a kid, it was playing demos in stores or renting a game from the local video store that would convince my brothers and I to buy a game if we liked it enough. Nintendo commercials and ads have always ranged from ineffectual to outright garbage (trying to sell EarthBound as a gross-out adventure being a good example of garbage).
The one time Nintendo's ad campaign was successful in selling a new concept (as opposed to selling something with characters people are already familiar with, like anything with Mario and friends), rather than just by word of mouth, was Pokemon. And in that case it wasn't even Nintendo's ad campaign so much as having a cartoon series on TV for kids to watch and become familiar with the characters. While a Fire Emblem or EarthBound cartoon would've done wonders for sales, producing a cartoon for every new game concept you're trying to sell isn't really feasible.
Having these games playing on demo stations in stores probably would've helped. Nowadays, having the ability to download Wii or 3DS demos (or download DS demos without the need for a Wii to connect) would help a lot more. And of course, having a marketing department that isn't incompetent would be helpful as well.
Have you seen the TV spot for Sin & Punishment? I love how the short snippets of gameplay (with visual effects on top, adding additional visual confusion to what's happening) left me knowing just as little about the game as I had before I first saw it (I hadn't heard of the series at the time). Apparently they thought just telling you it was a "hair-trigger shooter for the Wii" and then showing you a commercial that looks like it was storyboarded in 1999 would be enough to convince people to buy the game.
