I'm surprised myself. Sunshine was a rad title with a huge amount of content, and fairly challenging too. That stingray level outside of the hotel was nightmarish.Yeah, its a shame Pandora's Tower got so little attention. Both Xenoblade and The Last Story fared a lot better out of the Operation Rainfall games, and people really missed out.
To be honest though, I haven't actually beaten the game yet. I'm stuck on the 3rd tower.
