Hack: Money Cheat
NOTE: This involves editing a game file so create a backup before proceeding.

Locate the bgruppen.dat file in the drive letter:\1503 ad\data\ directory. Use a text editor (like Notepad) to open the file and search for the following lines:

Id: ALKOHOL
BauFirst: INFRA_STUFE_1C
Preis: 900
Bonus: 5, STEPPE|PRAERIE|DSCHUNGEL
PreisLevel: 0,5,10

Change the preis line accordingly and your people will pay that much as the "Price" of that commodity. The other prices can be changed (i.e., salz denote is salt), but be careful not to be messing up your whole game!
