While I do look down on larpers, I have to admit there is a certain geek in me that might find it fun, at least to play once. But Larpers and table top gamers will never be cool even amongst other nerds and geeks. There is just a certain anti-socialness amongst a lot of those people that many people just can't be around for long, plus almost no women. A deal breaker for guys who still care about getting laid.
Anti-social? Well, yeah, okay, some tabletop gamers and larpers won't associate with people outside the group. However, the nature of that kind of gaming assumes that you either have at least two friends or that you can get along well enough with other people to not get on their nerves too much for a couple of hours. The last time I checked, you don't actually
need friends to play a video game, even if you play online multiplayer matches.
With that in mind, I'd like to say that I know many very social and friendly gamers who partake in both video and tabletop gaming. Heck, most gamers of both that I've met are pretty nice people who I wouldn't object to hanging out with. Also, the presence of women in all kinds of games is increasing all the time. Roughly 50% of video gamers are women, and while there aren't as many women who LARP or play tabletop games, the numbers have increased exponentially from when the hobby was first conceived.
