There are a few ways to approach this. Ultimately, I don’t know the people, so it’ll be a judgement call on your part.
You’ve mentioned two categories already: Party Games and Hidden Role Games
For additional party games, I would suggest:
- Telestrations - this is a recurring favorite whenever we end up with more than 5 or 6 people at my house. I recommended making very specific guesses that intentionally steer the game in crazy directions… it’s never fun to start with a picture of a paper clip and end up with a guess of “paper clip”
- Bring Your Own Book - SUSD covered this very briefly a couple of years ago and I grabbed a copy when I saw it sitting on my FLGS’s shelf. It’s fantastic and we have used it more as a wedding/baby shower game than anything- leveraging kids’ books because there are always things that can be taken out of context and made funny and they are short and easy to scan/parse at a glance
Hidden Role Games:
- Coup (-ish? it’s lying to friends, so I think it counts)
- Whales Destroying the World (if you don’t already have this, it’ll be hard to find. But if you have it, definitely take it with you)
- Resistance: Avalon (best-in-class hidden role game as far as I know)
Additional categories to consider…
Light Strategy Games that can work at high player counts:
- RoboRally (keep the layouts smallish)
- Camel Up
- Sushi Go Party!
- Ca$h 'n Guns
- Between Two Castles of Mad King Ludwig
- Bargain Quest
- Wits & Wagers
- Flamme Rouge w/Peloton
- Going, Going, GONE!
Sales Pitch Games (sort of a sub-category of Party Games):
- The Champion of the Wild
- Snake Oil
- But Wait, There’s More
- Flash Point: Fire Rescue
- Mysterium (meh, we play this as full-co-op…)
- others? This isn’t a strong category for me
Roll & Write:
And of course:
Honestly, if these are non-gamers, I doubt you’ll convince them all to play a game more than once or twice. I would count on maybe having 3 or 4 player games available for those times that some of the people will say, “Ahh, nah, count me out this time”.
