It seems Spore will use your countrys language in-game, and as most know the translations aren't often that great. Most likely it's the language of your OS that dictates what will be used. After searching around I found a fix for this problem: Create a shortcut, select properties and change the shortcut path to "X:\XXX\Sporebin\SporeApp.exe" -L:english if you want it in english. The X'es will be the path for where you installed the game.
