Er, necropost, sorry, but I'm just going to do these one by one per game.
AA1: Cindy Stone. There's not much to her, but she's still alright, considering she actually did care for Larry in the end. Second place is Goodman. He's also kind of bland, but his backstory was a little more interesting.
AA2: Probably Dustin Prince. I guess he did care for Maggey and he was just doing his job, but pretty unremarkable. Turner Grey and Juan Corrida are both terrible people, but at least they're kind of interesting. Russell's probably the most alright. His design is at least more memorable than Dustin's.
AA3: Kane Bullard by a milestone. Even Maya thinks he's forgettable. Other than that, Doug Swallow and Glen Elg, I guess, though Doug's part in the story and Glen's design (as well as how it plays into 3-3) make them better than Bullard.
AA4: SO MANY JERKS HERE! Zak, Magnifi, Pal…though I do like their designs (especially 'Shadi' and Pal's toothpaste hair). Drew is pretty cool though, so I guess I'm going to have to go with Romein LeTouse. Seriously, look at that name. I have bad memories of that one flashback too, urgh.
AA5: I'm just going to say everyone sans Jack Shipley and Metis Cykes are the worst. They're all pretty much the same archetype, just good people who were at the wrong place at the wrong time, blah blah blah. Boring.
AA6: Paht Rohl or Manov Mistree. They both have horrible puns, though I do guess they were sympathetic in a sense. Part had to steal for his family and Manov was just a cog in a bigger scheme.
AAI: So many bland victims here. It's a toss-up between Buddy Faith, Akbey Hicks, Mack Rell, and Ka-Shi Nou. I would include Deid Mann here, but…he's Deid Mann. How could I? But yeah, these guys are just thoroughly unmemorable and their designs are just bleh.
AAI2: Oh man, this is kinda hard. Lots of interesting victims here. Probably Jack Cameron. Another unfortunate fellow just at the wrong place at the wrong time. Jill would be here too, but at least she had an interesting motive.
PLvsAA: I would say Robbs and Muggs, but then, wasn't there a town full of people who died from the Great Fire that we never got to know about? Yeah, them. That's a lotta people.
. There was something about his face that bothered me, and then that ONE picture, where it showed him discovering Celeste Inpax's body, he took ALL the seriousness out of the scene with his outrageous body language, super tight pants, enormous mouth, and that grass he chews on! And to top it all off, I blame him for her death; He left her because of his petty "male pride", if you could even call it that! Dang Corrida! 
and a certain Shadi fellow.
