Okay, then I have an idea!

Don't use "Take this %1 to the %2 and get a %3 as reward." for every quest in the game. Think about more original quests where each one has its own nice and descriptive text without placeholders. <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />

Just use a tool to group texts that belong to the same quest. When you translate one text it shows you all related texts. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
