Rounding out the Vietnam and Kublai Khan Pack update is a new district known as the Preserve, which can be built in secluded areas and is able to Culture bomb adjacent tiles, gain additional housing based on appeal, and increase the appeal of adjacent tiles. Those that successfully dominate the global supply of a luxury resource can create a Monopoly, capable of generating a massive amount of gold and Tourism, and if you want to learn more, additional details can be found in Firaxis' latest developer video. Once enough points have been accrued, Industries may be levelled into Corporations, and these can create Products to slot into the Stock Exchange and Seaport buildings, much like a Museum's Great Works. Industries provide powerful buffs to home cities - from increased yields to decreased production costs - alongside a steady supply of Great Merchant points. Firaxis has thankfully been a little more forthcoming about the new Monopolies and Corporations game mode, explaining that it's designed to offer 'more robust economic gameplay' focussed on creating Industries around duplicate resources.
