I’m trying create a small and handy summary of rules for a pen and paper RPG (a game master screen). So I have to deal with lots of small paragraphs and tables. My goal is to get much information on a few sheets of paper – as clearly arranged as possible.
I prefer scrartcl as documentclass (using DIV=15 for smaller margins). At the moment most of my tables (code below).

I’d like to arrange all of the slim tables in two columns (using e.g. multicol) on the paper to get as many tables as possible on each sheet (but there are also wider ones). This is a screenshot of a comparable word document

which shows roughly what I’d expect of my TeX output.
Any ideas how I can arrange the tables in a nice-looking and space-saving manner? I think floating tables are not useful here. And there is a limit of floating tables per page, iirc.
Which table environment(s) suit best to my needs and/or is there a "clever" way to handle those tables by creating an own environment? Sorry for being unspecific, but maybe someone else tried to create a "cheat sheet" like this with latex.
tl;dr: I need lots of tables and \paragraphs to fit well-arranged on less paper. Think of a cheat sheet for school, but nice looking and clear.
Here you’ve got an cleaned up TeX-file to get an idea of what my document looks like:
\documentclass[a4paper,10pt,DIV=15]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage{booktabs, longtable, multicol}
\title{Game Master Screen }
\begin{document}

\paragraph{another one} is eplained in tab.\,\ref{tab:extab}.
