Awesome card game.. It requires strategy and remembering several numbers in your mind.. If you only have the core game, it might get tiring if you play frequently, but due to the expansions (around 8), you won't easily get bored.. The only thing someone should be careful about is that if they don't get the English core and get the Greek one, in case they get expansions, they won't mix well with the Greek one since the English decks are bigger.. It's worth playing with 3 people.. Maybe the only negative thing is that the prices of the expansions are a bit steep..
