Nexon America, yeah? The people who brought us MapleStory and Dungeon Fighter Online among many other titles. Well, they've announced that Poptag is coming stateside, which is sort of Bomberman only fully online and with water balloons... So, it's definitely got a specific "thing" going on. While throwing water filled balloons may not quite match up to tossing explosives, the game goes for a fast paced arcade style that should still appeal to people looking for that sort of experience albeit with cutesy water balloon throwing characters.
And yes, this will be a free-to-play title with an item store, but that being Nexon's only business model thus far should've had you guessing as much already. But hey! The game also features a "sweetie" system that actually allows players to marry one another in-game proper -- aww.
Poptag is scheduled to be released sometime during the first half of 2010, so if you find yourself interested in playing, keep on the lookout.
