Thanks Rhodan. However, your points apply to anyone who buys plot first turn. I'm wondering more specifically about the strategy of selecing a river/valley plot first turn rather than a plain or mountain plot.
Most people I've seen select mountains, then put food or energy on them first turn. Selecting a valley ensures decent food first turn, but puts you behind in terms of non-valley plots. The question is, is it a viable strategy, and if so, how does one make IT work?
Production is fixed and if I remember correctly a random factor of plus or minus 3 is applied to each plot.
Example a river plot starts out producing four units vs a mountain plot of one unit.
Then the factors of plus or minus 3, adjacent plot, global events and rule of three bonuses are applied with max production of 8 possible. So a river plot will produce more food over 12 rounds then a empty or mountain plot. Thereby making recovering from 1st round plot purchase quicker.
The key is making sure you still acquired 9 mining plots in addition to your river plot for the rule of 3 bonuses.
Everyone goes for crystite plots so the only disadvantage to grabbing a river plot is
You don't get a stite plot that round
You make it harder to get the magic 12 mining plots.
