LogFAQs > #921250438

Thanks for following this topic to the end and giving plenty of suggestions. It is apparently pretty difficult to make writeups on characters I am not always completely familiar with, but I'm glad they turned out ok in the end. I think I identified most of the major errors in the bracket, mostly due to my own bias and occasional lack of oversight. I did have a hard time separating Gfaqs contest strength from affecting seeding too - probably since I was doing match analysis.

I will start off this post on snubs by going over Metalmind's suggestions, and then talking about other snubs I identified in another post. I'll probably respond to the seeding and removal suggestions in another additional post:

Cecil Harvey - And let the bias begin. I am familiar with FFIV and considered many characters from it. My having played the game went against Cecil; his struggles with morality in the game made me roll my eyes. It felt like he was a Dark Knight in name only, and he only had inner darkness because the game said so. But that is discounting the fact that his struggles were unique and groundbreaking at the time, so Cecil is ultimately a valid snub here.
Clyde - I don't think that having a unique attack pattern makes Clyde particularly influential. You could glean characterization from that, but I don't think that is a common thought. No on this one.
Creeper - I know next to nothing about Minecraft, but it isn't a particularly character-focused game. It has a somewhat unique manner of attack and is well known, but I don't think it does enough.
Doomguy - The problem with him is that he is just a mostly unseen player avatar, and doesn't even have an official name. He filled his role perfectly well to allow players to insert themselves into a bad*ss demon killer. But his complete lack of personality until the reboot hurts him too much here.
Lee Everett - I don't think Lee is suitable here for two reasons. He is notable as a minority protagonist, but it wasn't really groundbreaking circa 2013. Also the "revival" of point and click adventures only lasted for a few years, so any influence he had was very limited.
Ms. Pac-Man - "It's just Pac-Man with a bow" was the thinking that kept her out of the original bracket. But she was possibly the first female protagonist in gaming, and even had some personality shown in her developing relationship with Pac-Man. Very valid snub here.
Pauline - Overlooked her here, she is a valid snub. In fact while looking for snubs, I noted another early damsel in Princess Daphne from Dragon's Lair. She is one of the earliest examples of an overtly sexualized female character in games.
Red Bird - Um, no. You even admit he isn't influential.
Sans - Yeah I got nothing here. If he is a big part of Undertale like you say then maybe he is valid here.
Space Invader - Pretty valid snub for the reasons you stated.
The Avatar - Absolutely a valid snub. One of the first notable customizable protagonists, and the groundbreaking use of a morality system for him/her.
Companion Cube - No on this one. The cube itself doesn't do anything but look vaguely cute. It is the game itself/GLaDOS that makes you care about the cube.
