18NL is an 18xx game based on the 1830: Railways & Robber Barons rules adapted to the Netherlands. As in other games in this genre, players buy shares in railway companies, and then the majority share owner operates their companies by laying track, placing stations, and purchasing trains. 18NL has both been published as a standalone game, and as a print-and-play version. The latter version requires some components from 1830: Railways & Robber Barons to play.
