Guild Wars is kind of a fun game. It's nice because it's a massively multiplayer role-playing game that you can play for free.
But, hidden away in the menus is a little option you probably didn't know was there.
Open up the game and go to your options screen (or hit F11 for a handy shortcut). Under 'Text Language' check out the bottom option.
Select that option and marvel at how the text magically changes to resemble that of the mush-mouthed muppet, the Swedish Chef.
Everything changes, your quick stats,
the ad for the store
the tooltips that show what your items do...
Everything.
To get it back, just hit F11, and select whatever your default language is. The language setting is in the top portion of the first page of options that you have to select, so it's real easy to switch it back if you want.
