I can see why people would be upset about a game being "condemned" purely because of the length of the game. I agree that playtime most certainly is not everything, and while I don't think a good game and a long game are mutually exclusive, I don't think a game has to be long to be good. Personally, I think it's the price that has most people up in arms. It'll be a damn shame if the game is good, but the price ends up blacklisting it.
While I've been somewhat harsh with my comments and anti-cinematic views, I'll say that I don't want this type of game to fail, but rather that the developers learn from the experience and market things differently in the future. I felt this way when reading some of the comments in the interview regarding social gaming, movies, and Call of Duty. Those things are all very different, and they're marketed differently. Call of Duty is short on the campaign, but long in the multiplayer. Social games are typically short and casual, but are often free or cheap to buy into, and movies are... well, they're movies. Just as all of these are marketed differently, I feel that "cinematic" games need to be marketed differently as well. Especially considering that the cinematic connotations often denote shorter playthroughs and a lack of replayability.
You just have to know what you're making, where it fits, and how to sell it. But anyway, I'm getting long in the tooth over a game that I've neither played nor seen much of outside of trailers. That's NeoGAF for you, I guess.
