I don't know how best to state it, but it just felt that Battle of the Bands wasn't really fufilling. It was basically a series of fetch quests tied together, and Strong Bad was the AWESOME FEDEX OFFICER...I know that adventure games are usually composed of fetch quests, but it just felt the Fetch Quests was turned onto the Max. The jokes were decent, but it felt that the jokes was basically 'payment' for me doing what was basically 'busy work'...and, er, I hate work. That why I play games.
And the ending of the game was really an unfunny slap to my face. Really was. I'm sorry, but I really did do all that work just to play the Limozeen Defender Clone, and to find out that Strong Sad could have fixed the Fun Machine in about 5 seconds...was an upsetting shocker.
Now...it was a great joke if somebody was playing the game for the sake of playing the game, if the Limozeen Defender Clone was nothing more than a McGuffin and we never had any chance of playing it. But...it wasn't a joke to me. I really did feel upset that I did all that 'work' for nothing.
Now, I loved Ep. 1 and Ep. 2 (especially Ep. 2 where you fought against the KOT). They were great. But Ep. 3 didn't really feel oh-so-great. It was decent, but...it felt like a decline compared to those classics. The mini-games have the potential to keep people liking your game. You took out Teen Girl Squad but luckily, Limozzen Defender Clone filled in the void nicely. But I don't think a major game should rely on Mini-Games to keep interest...which is a shame.
I think you may be able to recover, with the release of Dangersque 3. And the game was still somewhat fun. I just am a little disappointed, just all.
