So here is an idea for an alternative to the current mode of play.

In this mode you can't buy stock and for the first 5 mins everything is normal but after that time if you have the highest debt for a consecutive period of time you get eliminated.

In case there is any confusion about what I mean by consecutive period of time, imagine if it was on 120 seconds to eliminate a player.

If you move from highest debt to second highest at the 119 second mark and immediately move back to highest debt you would get another 120 seconds to do something about it rather than being eliminated after one second since it is not cumulative.

This means there can be a lots of back and forth, players could survive for a long period even with a short elimination timer.

More players should lower this elimination time for example it might be 120 seconds on 8 players but 240 on 2 players.

I assume last man standing wins and instead off displaying a players stork price display there debt and how much time they have left if they are the highest debtor.

Alternatively you could have the elimination timer be cumulative but have it count in the opposite direction if your not currently the most in debt with the elimination timer thematically being how much attention you have from the debt collectors.

Edit: i forgot to mention that after the 5 min mark players slowly gain exponential additional debt to make sure its impossible to not have debt at the end game, also players that are eliminated become neutral A.I players but every now and then some of there stuff should go up for auction.
