How hard is it to understand?
There can be many Nash Equilibriums.
Especially in a 5 x 5 matrix. 
The demand for tobacco is given by:
q = 100,000 (10 - p)
where p is the price per pound. However, there is a government
price support program for tobacco that ensures that the price
cannot go under $0.25 per pound. Three tobacco farmers have each
harvested 600,000 pounds of tobacco. Each must make an independent
decision on how much to ship to the market and how much to
discard.
a) Show that there are two Nash equilibria, one in which
each farmer ships the whole crop, and a second in which each farmer
ships 250,000 pounds and discards 350,000 pounds.
b) Are there any other Nash equilibria?
