Note: This procedure involves editing a game file;
create a backup copy of the file before proceeding. Use a text
editor to edit the "bgruppen.dat" file in the "1503
addata" folder. Look for the following entries in the file,
about one fifth of the way down.
Id: ALKOHOL
BauFirst: INFRA_STUFE_1C
Preis: 900
Bonus: 5, STEPPE|PRAERIE|DSCHUNGEL
PreisLevel: 0,5,10
Change the price ("preis"), as already done, to "900"
and your people will pay it. Obviously, other prices can be changed
("Salz" is salt, etc.), but be careful. Do not mark
up something that you plan on importing.
