Martin Osborne has a powerful guide on creating bimatrix for game theory https://www.economics.utoronto.ca/osborne/latex/
I am not familiar as to how I can incorporate a .sty file to my latex. I was expecting to use a package instead.
Can anyone teach me how I can use the .sty file so I can gain access to library of commands such as
\begin{game}{2}{2}
…
\end{game}
\documentclass[12pt]{article}
\usepackage{multirow}
\newcommand\ml[1]{\multicolumn{1}{|l|}{#1}}
\newcommand\mcc[1]{\multicolumn{2}{c}{#1}}
\begin{document}
\begin{center}
\renewcommand\arraystretch{1.3}
\begin{tabular}{lc|c|c|}
\mcc{} & \mcc{Suspect 2} \\
\cline{3-4}
& & Quiet & Fink \\
\cline{2-4}
\multirow{2}{*}{Suspect 1}
& \ml{Quiet} & 4,4 & 0,6 \\
\cline{2-4}
& \ml{Fink} & 6,0 & 2,2 \\
\cline{2-4}
\end{tabular}
\end{center}
\end{document}
edit: as suggested CarLaTeX in her comment below, table is now stretched by factor 1.3.
Just for fun: matrices that auto-create their entries.
\documentclass[tikz,border=3mm]{standalone}
\usetikzlibrary{matrix}

With a more linearized treatment of the cases (certainly not the optimum).

\usetikzlibrary{matrix}

execute at begin node={%
$\vphantom{x_1^1}
\pgfmathtruncatemacro{\itest}{sign(4-\the\pgfmatrixcurrentcolumn)*sign(4-\the\pgfmatrixcurrentrow)}

Best Answer
A .sty file is a "package". Since the
sgamepackage (which meanssgame.styand accompanying documentation) resides at CTAN.org, there is a good chance that your LaTeX installation will automatically know how to download and access it merely by placing\usepackage{sgame}in your document preamble.
