As noted in Christian Hupfer's answer, the package `sgame`

is incompatible with `array`

. Is there a more tolerant alternative for typesetting payoff matrices in game theory?

MNWE:

```
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[]{array}
\usepackage{sgame}
\begin{document}
\begin{game}{2}{2}[You][Your partner][Prisoner's Dilemma]
& Talk & Quiet \\
Talk & $-10,-10$ & $-1,-20$ \\
Quiet & $-20,-1$ & $-5,-5$
\end{game}
\end{document}
```

produces an error, as expected:

```
! Missing # inserted in alignment preamble.
<to be read again>
\cr
l.26 ...{2}[You][Your partner][Prisoner's Dilemma]
?
```

Note that I realise I can do this without a dedicated package in any number of ways. I'm asking if somebody has already invented a wheel of the kind I seek.
