For anyone starting any new game I would advise to it at the easiest level, if there is any. That is what always do where ever possible and then progress to the highest and most difficult. For example I now play Colonization at the Viceroy level! Had I tried it when I first got, sometimes in early Nineties I may have had to give it in frustration
! But then there are games, I think all Sierra games, where there is no choice and it's a matter of hit and miss, trial and error - the only way you can play it.
So good luck. One learns from experience rather than active help or simole advice!
