I didn't watch any other ones
So I had no idea what was going on, but it was a kind've funny parody of Captain N: The Game Master, nonetheless. Man, that show was corny...
Could've tried harder at making Sonic sound more Sonic-ish. One of his prime traits is that high pitched, always overly-enthusiastic voice, which could have been pretty funny to reproduce. You also could've taken more advantage of being able to make fun of the Sonic characters overall. You didn't bash on them enough, and they're easy targets. Actually, you didn't bash them whatsoever.
You didn't put seriousness into them to make them seem genuine, nor did you put sarcasm into them for humor, so I'm not sure what you were trying to do. I'm no professional critic, but, if you're going to parody video games, you should kinda, you know...parody them in some fashion.
Could've definitly been funnier. Voice acting could've been better, too, but some of the voices *were* pretty funny (Kirby & Ganon). I think this thing can be done up better overall, especially if you're working with multiple people on it. J'mon now.
