Do MMO crossovers break your immersions?

When I was a kid, I read a post-Vietnam fantasy novel called Doomfarers of Coramonde that should have ruined crossover fiction for me forever. I just couldn't take seriously an Army hero whisked away by magic and plunked into a world of dragons and castles and sorceresses.

MMO crossovers can likewise break my immersions. I'm not talking about sequels, and I'm not even talking about the unholy marriage of EVE Online and DUST 514. I'm talking about Funcom putting leet pets from Anarchy Online into The Secret World's cash shop, which is a thing that did in fact happen yesterday. It joins the Ultima Online ankh necklace my character wore in Warhammer Online on the list of bizarre cross-MMO promotions that really don't make a whole lot of sense in-character. Why in the world would my character in TSW have an adorable leet pet from the the planet of Rubi-Ka? What's next -- cupid wings on Ewoks? Oh. Right.

So what do you think, morning crew and minipet-hoarders? Does this sort of promotion satisfy some deep craving, or does it just break your immersions?
