Two Guys is definitely making it. No doubt. The stream of backers and $1000+ per hour has been amazing this past week. I don't know what did it. A couple of weeks ago the chance of success was very slim.
Between Two Guys Spaceventure, Tex Murphy - Project Fedora, Jane Jensen's Moebius, and Double Fine Adventure, I'm so happy as an adventure gamer. This is the resurgence I think many of us were waiting for. Adventure games never went away, and there have been some amazing titles in the last 10-15 years, but seeing all these older developers take back the genre from publishers is very exciting.
