A friend of mine introduced me to a game years ago she called "Celebrity". It wasn't a game you bought, you just had everyone write down a famous persons name and then, similar to Rabble, you had 3 rounds to have your team guess as many as possible. This is a physical copy of that game and is just as much fun.
There are 2 versions of Rabble, the original and the travel version. The difference is that this version has less cards (to make it a bit more portable) and all of the cards are travel related. They both state the same number of players and time.
The game is a LOT of fun. Even if you play over and over, it will never be the same since different clues will be used and everyone is going to do the charades much differently. No matter how many times you play it, it will ALWAYS leave you laughing. We took it to Thanksgiving and played twice with family and everyone was laughing during our 2 plays. Even my brothers (who normally don't like games) played and even got up to do the charades round!
The game says 17+ and includes some NSFW cards. I have to give credit to the designers though as they separated out these cards put them UNDER everything else and clearly marked them "Naughty". If you remove these cards from play, I can't see why you couldn't play with people under 17 (although some of the cards might be too hard for kids under 13 or 14 to know enough of to give good clues).
The game is easy to learn. The rules are clear and not long at all. You may have to refer back to them for the first few plays for the scoring, but we didn't keep score we just played until one team got all of their cards guessed each round and the team that won the most rounds won the game. No one really got upset since we were all laughing so much though.
I think this version of the game is a great game to take with you to game night or family functions as everyone can play. It is small enough that you can throw it in a bag and not have it take up too much space and it can handle as many people as you like. You can also break it down into more then two teams if you want. After playing this, I actually plan on buying the full size version as well, that's how much we liked it!
