There have been some players complaining that debt does nothing and on game Blackmagic had 800k debt and still won the game?(idk how much) And I can see a point in why they could complain. I have seen some games where a player with alot of debt will buy alot of stocks of his opponents wherefor his stockprise rises like anyone else but the debt doesn't reflect on his stockprice.(only his own 10 stocks)
Now you have it so that D rating will disable Blackmarket there should be another penalty for having too much debt.
3 Options:
1. Debt will work on the entire Stockprice ( So Not that i got 800k debt which would mean I have a 1$ stockprice if it weren't for the stocks I bought from other players which still gives me 1$+ a stock most of the time but every Stock*0,?debt=your stockprice )
or (the better one)
2. Have another Penalty when you reach 300k(whatever the number must be). The Penalty would be that All special buildings would be in lockdown. So you can't Hack/Patent/Train/PleasureDome/or send an offworld while you are in set numer debt. Maybe even Cancell out there patents/Upgrades ( or have that on another penalty which would be 400k orsomething)
3. if you reach set number debt your company's cash will first pay of his debt automaticly (like tighter debt)
