I wonder if bonus that clearly intent for offer new style of gameplay should be removed? Example are various bonus characters from Castlevania series. Sure, they can't do same thing as main character did (item equip and such) but each of them alway have some abilities that lets player go through most of game with alternative method, clearly they are there for Rule Of Fun.

It seems like this page could do with a tighter definition, maybe along the lines of "the unlockable loses functionality so as to be inferior in gameplay to the default features". Most of these seem to range from Bragging Rights Rewards, to Cosmetic Awards, to just plain complaining that you think the reward wasn't very good.

Shouldn't this be turned into a YMMV trope? The first example of this I came across had someone saying YMMV about it.

I'm not sure if this applies but Criterion Games managed to piss off the entire PC userbase with their Burnout Paradise release. More specifically, their refusing to release two major DLC packs for the PC: Cops & Robbers and Big Surf Island.
