A few clarifications:
First off, this is in no way an official announcement. We're meeting today to finalize our plans and write up the proposal. I have been assured that we're free to do it at the con, but it's last minute. If we do it, we want to be sure to do it right. If we can't do it right in the time we have, we'd rather put it off a year.
Second, once we DO have an official announcement, I'll be sure to post here (as long as that's ok w/ the Mongoose folks).
Third is that it won't be a boffer game, but so long as it's just for show, a giant wrench might be fine. We'd clear it at registration. We're also not going to expect people to have Paranoia-specific clothing to wear, but if you do that's great. Might even get you extra consideration as it will prove you're familiar with the setting.
Fourth I'm glad you're interested! Everything is in flux at the moment (see above) but once I have solid details I'll let you and everyone else know.
On to your recommendations!
1) our badges are big, character names are big, clearance levels are stuck right to the badge with color stickers. GMs will all be High Programmers, so white will make them easy to spot. Bots will have something to make them distinctive (like a tin foil armband, for example). NPCs will end up treated just like PCs for the purposes of the game, and won't be responsible for rules disputes anyway, so no problems there.
2) See above. Clearance levels will be clearly defined and easy to spot. That is something we made sure of right from the start as it figured prominently into our badge design requirements.
3) This one is tougher and I'll be sure to mention it. As it stands right now, I think we're doing item cards, but I'll try to figure out a way to make weapon cards stand out from the pack.
Our rules system is kind of in flux and I don't want to go into it until it's finalized and play tested. It won't be boffer, it won't be P-R-S, and it will resolve very quickly. That's all I'm comfortable saying right now.
