It's a shame, really, and you should seek to remedy this. If you're having trouble, try just replacing an 'S' with a 'Z', a 'CKS' with a 'Z', or, if you're feeling really adventurous, replace an opening 'Z' with an 'X'!
Ex: Daxter, Zelda, Vaan, Jenova

All Your Favorite Words Overused? Combine Them for a Fresh Approach

Disclaimer: Though I poke fun, I am quite a fan of unusual names. I don't want Larry the hero and Sue the love interest.
Disclaimer: Sorry, Larry's and Sue's. I'm sure you're all nice people.
