Neptune's Pride

Neptune's Pride is a 2010 browser-based 4X video game, created by Australian studio Iron Helmet Games.

Production
Neptune's Pride was partially designed by Penny Sweetser, whose doctoral thesis focused on emergent play as a design strategy.

Gameplay
Players can produce, research, explore, and colonize star systems. The goal of the game is to capture a specified percentage of all total stars; a game can last for up to a month, or even longer, with events progressing in real time, even when players are logged out. Diplomacy is an important part of the game, with alliance-building and betrayal of allies playing a major role.

Reception
PC Gamer UK named Neptune's Pride as Webgame of the Year.

In 2011, it was listed in the book 1001 Video Games You Must Play Before You Die.
