I played Rainbow Moon for over 30 hours on hard difficulty and still have so much more to do on both the main quest and various side quests I encountered. A representative from the developer told me that he spent more than twice that much time with the game, and that even shooting through the main quest on standard difficulty without exploring and doing side quests will take longer than my time investment. This is only supported by the fact that there’s a Trophy for spending 100 hours with the game, a Trophy that won’t be difficult to obtain if you really try to see and do everything in Rainbow Moon. Rainbow Moon also has a Platinum Trophy, a rarity for downloadable games, so the investment may very well be even more than that.
At the end of the day, the rub with Rainbow Moon is that it’s a time investment, and it’s not a time investment those of you who don’t like grinding RPGs will want to make. But for those of you that do enjoy a solid, old-school grind, spending time with Rainbow Moon is time well spent, especially considering Rainbow Moon costs a meager $15. Put bluntly, that’s a hell of a value. Put more bluntly, Rainbow Moon is a lot of fun, and RPG fanatics should play it.
