While I can't always agree with you Noizy, I agree there. Word of mouth has killed the scene for several fighters before. Either bad word of mouth, or not enough word of mouth.
But true, it comes down to personal preference since what one person likes may not be appropriate for others. I love playing Rez (Happy 420), but a lot of people can't get past it's primitive graphics, and techno'ish soundtrack. However, that fact won't kill the hype for a game, just make it more of a mainstream, or a niche title. Word of mouth, like we've seen for SFxTekken, can hurt a game's potential future sales and hype, where as not enough word of mouth, like for KoF13, could hurt it's sales too, regardless of how hyped people are for it.
