Well, the story wasn't as powerful as the third game, but the gameplay was better... or perhaps I was just used to it by now. The story was a bit funnier, but I still don't know how 'Penny Arcade-y' it is, especially when looking at the first two in the series.
The music finally worked! The third game's tunes would not start, no matter what advice I followed, and I must say, I quite like the soundtrack. I expected chiptunes garbage but this was pretty good.
I didn't like some of the characters, but because writing and interaction took a backseat in these games, I guess it's not too big of a knock.
Basically, every time I try to come up with praise, it's always weakened by some qualifier, or a reminder of what was done poorly. I'm sorry, Zeboyd, but I don't like your games, and I'm done writing about them.
