While it is rare in the English market for online games to have TV commercials airing, it is quite the norm over at Japan, although I am not sure about Korea. ArcheAge Japan launched earlier today, and 2 TV commercials were brought to the living room screens over there.
ArcheAge Japan is still retaining the monthly subscription model, despite the Korea version has embraced Free-to-Play. There is still no news about the North America and Europe server, but I don’t see any substantial updates coming till later this year.
