So, I just beat Pandora's Tower (Wii) and I'm pretty impressed at how solid it was. It always looked like the least interesting of the Operation Rainfall games, but it passed my expectations by quite a bit (and I'd probably put it above Last Story, but I haven't played Last Story in years). If I had to describe it, I'd say it is kind of like a bunch of Twilight Princess hookshot dungeons with a bigger focus on combat than puzzles. Some of the bosses are pretty killer (although there are a few I hate) and the game was a lot of fun to play. There's definitely stuff holding it back, but if that description sounds interesting to you and you can find it for a decent price, I'd definitely recommend it!
