Why did ICO and Shadow of the Colossus have such low sales?

For the same reason No More Heroes and Madworld have low sales: they are niche titles. Only a small portion of gamers are interested in that style of game, so not many people buy them.

But like 95% of the people that play either of those games consider them to be the best of all time, you'd think word would spread, and people would at least give it a try, it should of had good legs.

I really hope Team ICO's new game for the PS3 get's advertised the sh*t out of it, everyone needs to know about this company.

Wii fans have been sayin the same stuff about No More Heroes.  It's unique, fun, has great art and personality and controls, and is so niche that nobody noticed.
