Simple question... Should we allow custom stadiums? If so.. here would be the rules: Stadium Factors: Stadium Factors are used to change 6 ratings for each stadium AVG vs. LHB AVG vs. RHB Doubles Triples HR vs. LHB HR vs. RHB All stadiums start with values of 1.00 for each rating. To change a factor by .001 costs .1 stadium factor (i.e., to raise AVG vs. LHB from 1.000 to 1.013 costs 1.3 stadium factors) All stadiums start with 45,000 seats Any changes above .075 cost double. So, to raise AVG vs. LHB from 1.000 to 1.100 costs 7.5 + 2.5*2, or 12.5 stadium factors. To add 5,000 seats is 10 stadium factors Each team would have 40 stadium factors to customize their park.
