I think it'd be wonderful to have the command just for kidnapping, because half the time I've tried to roleplay people that way, they ignore it or just run for it. A command that makes the real thing go on would be very useful.
Also, as for your comment about people dancing in .2, it is quite fun. What you saw were videos from Beta Testers who are building their own servers on the site. I've been on one myself, and .2 is looking quite good. Found a dancing glitch already, though. If you enter the dance command on a bike, you dance through the bike, but can still drive! Quite amusing really.
Point is that /kidnap (amount) command would be really fun, and add surprise to it. Most people roleplay it as a preset response. The kidnapped knows whats about to happen and says okay with it. With the command, it's usually they get in a car, someone uses the command, and then it's sprung on them. They can try calling people to help, screaming and whatnot - and to even add a realistic aspect to it, you could also add in that when your under the influence of the kidnap command, you can say (/l) and shout (/shout), but the main chat is inaccesible, to give it that sort of challenge.
Also, the kidnap command itself could be set to not always work. Sometimes the kidnapped might be ejected from the vehicle and would be able to run away without being captured. The command would add a new tenseness on getting into cars with strangers, that's for sure! :conf:
