Are there some nice properties for a finite two-player game having an increasing differences utility and a decreasing differences utility?

Nice properties of the set of Nash equilibria can be shown for supermodular games(see here). But for a two-player game in which

1. Strategy spaces for two player, $S_1$ and $S_2$ are finite, and both of them are subsets of $\mathbb R$.
2. $u_1$ exhibits increasing differences while $u_2$ exhibits decreasing differences.

What can we say about it?
