Now I've read it and I'm going to try keeping my comments about it spoiler free.
First: Dynamite, in these two comics (SWORDQUEST and CENTIPEDE) is definitely going out of its way to create comics that are ABOUT the video game referenced in the title, but that don't tell the story OF the video game in the title. In this case, CENTIPEDE is not about a little guy protecting a garden from centipedes and spiders and whatnot. Not even close. However, if look at the game's components, it's all there.
Second: I know I would like the story if it was not related to the Atari branding, but I don't know if I would buy it if it were not related to the Atari branding.
Third: So you can know what you're getting into... This is a post-apocalyptic, "last man on earth" type of story with a meta-textual narration. At first, especially with the dialogue/narration I wasn't sure I was going to like it. And there were some moments where the writing did not connect with me. But over all, the main character was likable enough and the story interesting enough for me to come back for the next issue.
Anyway, that's my two cents. I AM very curious what other people, especially other people in the target audience (people with nostalgic connection to Atari) think about it.
