We were introduced to Colossal Arena through my wife's sister and loved it so much we decided to order it as soon as we got home and so we did and it arrived and is great. Fairly easy game to explain and a good measure of luck vs strategy but just a really fun occasion with none of the tenseness that can be associated with some competitive games. Quite a quick game as well so maybe 30 to 45 minutes for a game. Really a worthwhile addition as a fill in between some longer games of Settlers and Stone Age...
