Generando una matriz de pagos 3x3 (Teoría de juegos)

Question

He estado trabajando en algo de economía últimamente y pude descubrir cómo armar algunas matrices de pagos de 2x2, pero no estoy seguro de cómo hacer una de 3x3. Me gustaría mantener la misma idea general si es posible, es decir, la imagen tikz.

Esto es lo que he usado para generar un 2x2.

\matrix[matrix of math nodes,every odd row/.style={align=right},every evenrow/.style={align=left},every node/.style={text width=1.5cm},row sep=0.2cm,column sep=0.2cm] (m) {
2&\bf{3}\\
4&\bf{2}\\
-1&\bf{0}\\
\bf{6}&0\\
};
\draw (m.north east) rectangle (m.south west);
\draw (m.north) -- (m.south);
\draw (m.east) -- (m.west);

\coordinate (a) at ($(m.north west)!0.25!(m.north east)$);
\coordinate (b) at ($(m.north west)!0.75!(m.north east)$);
\node[above=5pt of a,anchor=base] {Left};
\node[above=5pt of b,anchor=base] {Right};

\coordinate (c) at ($(m.north west)!0.25!(m.south west)$);
\coordinate (d) at ($(m.north west)!0.75!(m.south west)$);
\node[left=2pt of c,text width=1cm]  {Up};
\node[left=2pt of d,text width=1cm]  {Down};

\node[above=18pt of m.north] (firm b) {Column};
\node[left=1.6cm of m.west,align=center,anchor=center] {Row};

%\node[above=5pt of firm b]  {Payoff Matrix};

Por favor echa un vistazo a¿Los comandos de estilo de fuente de dos letras (\bf, \it,…) alguna vez resucitarán en LaTeX?
