It very much does factor into Catan. Not only are there no spaces marked "7", which is instead used for a special type of result, the probability of the remaining rolls are described graphically on the number tokens: http://www.catan.com/files/styles/lightboxy/public/gallery/dye_catan_150618_0650.jpg?itok=9RJRSUjI http://www.catan.com/files/styles/lightboxy/public/gallery/d... Notice that the 12 has one dot, the 9 (6+3, 5+4, 4+5, 3+6) has 4 dots, and the 3 (2+1, 1+2) has 2 dots. The gray robber piece is sitting on a red number token, which is either a 6 or an 8 and has 5 dots because it is more likely to be rolled. In the game, you develop your pieces with the hopes of getting resources based on the adjacent numbers being rolled. It definitely creates a lot of stress in some people when "eights are being rolled all the time this game but never sixes!" or "your stupid 10 keeps getting rolled when it shouldn't, that's not fair!" I think I'll give it a try tonight with some numbered cards. I just threw some together in Excel: 1-6 in B1-G1, 1-6 in A2-A7, and the formula =B$1&" + "&$A2&" = "&(B$1+$A2) spread across the grid and printed that out, but on doing a little, ah, market research, it looks like you can buy official Catan decks like this at https://boardgamegeek.com/boardgameexpansion/20038/catan-event-cards https://boardgamegeek.com/boardgameexpansion/20038/catan-eve.... Or download this: https://boardgamegeek.com/filepage/40420/deck-dice-separate-cards https://boardgamegeek.com/filepage/40420/deck-dice-separate-... (note: not the above). Or someone else pointed out that you can simulate it with two matching decks of cards with: one 2 two 3S three 4S four 5S five 6S six 7S five 8S four 9S three 10S two Jacks one Queen Other market research says that people start counting cards to see when their numbers are going to come up again....perhaps some compromise, with perhaps two or three such decks? Real dice are an approximation of an infinite number of shuffled decks of dice, and I imagine you'd go through on the order of 100 'cards' in a given game, so with more than 3 or 4 decks you could end up with certain cards/numbers that never appeared, which seems to happen frequently and cause ire in games with real dice...interesting. Science is required! Sorry for rambling/thinking out loud.
