I've been playing a lot of Prime World in the last few days. Prime World is a new MOBA game that adds MMORTS and MMORPG elements to the overall adventure, as well as a series of single player quests. None of this can count as reinventing the wheel, but it works. It feels fresh and fun without ever feeling as "by the numbers" as the average game in those individual genres. It doesn't need to be as good, it just needs to try something original.
How long can this go on for though? How long can we just blend genres before we run out of genres to blend?
