Let's face it, we hardcore gamers are always looking for an excuse to play ninja dress-up. After obliterating tens of thousands of nameless, demonic foes, what greater satisfaction could there be than in donning a leopard print bodysuit and doing it all over again? That's the thing, palette swaps used to be bonuses for our hard-earned mileage; easter eggs buried at the end of the playing field. Not premium DLC.
In the real world, buying a sassy lil' getup can be a cathartic release. In virtual land you just feel like a chump. So Tecmo, Team Ninja, Microsoft, whoever, take your Ninja Gaiden "horse armor" and shove it!
