Wow. The sexism in this thread is...completely unnecessary? But sadly not that surprising...
I didn't see the OP as saying her opinion was more valid or getting excited because she's a woman. But considering roguelikes are generally a pretty niche genre, it is kind of cool to see someone famous posting about a roguelike (an ACTUAL roguelike, too, not just a "roguelikelike" such as FTL or Isaac) especially someone famous for talking a lot about games. Doesn't mean her opinion is more valid, but let's face it, famous people's endorsements carry weight with a lot of people (that's why they're so many commercials), so chances are it'll expose the game/genre to more people who otherwise wouldn't have even heard of it, let alone been interested.
Of course, there's certainly some people around here who would see more people coming in as a bad thing, that a bunch of people who aren't "real" roguelike fans (or god forbid just a bunch of girls who like to play with dolls) will somehow dilute the brand, but if you like to play roguelikes, more attention on them is a good thing because it means people will be more likely to make them to tap into that market. If you like to make roguelikes, it's even better because the potential players for your game increases.
So, anyway, thanks for posting this, bencollver.
