Alright, suit yourself. Instead of focusing on more needed features (graphics, game-play, networking, etc etc) go ahead and gander your time away on this "easy" feature.
When will Russian be supported? Perhaps French? Maybe Spanish, Chinese, Arabic, Portuguese, Japanese, German, Korean, Italian, Polish, Persian, Thai, Romanian, Dutch, Greek, Czech, Swedish, and Slovak? Hopefully soon since those languages compose 90% of your client-base, and since your devoting so much time to such an easy feature.
Do note that in the early stages of a game the text changes very often, and each release the dictionaries for each language will have to be re-translated (this compounds in later stages, when large amounts of text are in the game).
No really, coming from an experienced developer and team-lead, saving the language crap till the end is the way to go. But, do whatever you see best.
PS: Oh, and ((Multilingual != Unicode) == false), whereas ((Multilingual == Unicode) == true)
