Lets assume a VERY short code. Just 12 letters long. We still have over 95,000,000,000,000,000 combinations. Lets assume 95 million copies of FM are produced. Yes, it's the best selling game ever, by a long long margin.
We still have 1 real combination in every MILLION combinations. Unless i've done my sums wrong here, that means that a selection of 12 letters would work perfectly, with a million to one chance of randomly getting it right. Add a 13th letter and you up that to 1 in 26million, even with 95million "real" codes. At 14, you have a one in 676million chance of getting a real code... Yes, with 95 million real codes in existence.
Do the extra 10 combinations make such a huge difference? With 12 letters, it has 50 times as many combinations. Make it 12 of a-z or 0-9 vs 13 just a-z and the alphanumeric is only twice as many codes. At 14 sets of digits (a-z) vs 12 sets of digits (a-z + 0-9) we suddenly have 13 times more combinations with our set of 14 digits.
So, would anyone here rather of had to enter two more letters rather than deal with numbers AND letters in the code? And just think, it'd be 13 times more secure at that!
