This trailer offers a two-minute introduction to LeapDrive Online, a spaceship-based roguelike-like action/RPG featuring procedurally generated gameplay and what they are calling "social exploration." This is a web-based game is being developed by one individual who is showing it off now that it's in a playable state to support its Steam Greenlight campaign as well as the next stage of development, which will be a major rebalance. Those interested should head over to the LeapDrive Online website to register for the closed beta. Here's more on the game:

LeapDriveOnline procedurally generates a massive "maze" (called The Maelstrom) of connected regions of space (called Cells) much like a normal rogue-like game, BUT each instance of The Maelstrom is shared among a community of players. All of the players begin at the same location at the edge of The Maelstrom, but they need to explore The Maelstrom to find a path to The Core. A number cells contain "beacons" which allows the player to start their next journey from that cell (you can think of this like a spatial save-point).

Built into the heart of the game is a system for sharing paths that players have found. If I, for example, find a powerful relic in a cell, I can send you a path to reach that relic which you can follow. You still need to reach the relic yourself, but the path to reach it will be marked. In the end, the game is a race, with individuals and clans trying to reach the core of the maze. The enemies you face will increase in difficulty as you approach the core, and there is a rich system of ship upgrades to make your ship more powerful as you play.

Some people will share information with others, and some people won't. To make that decision more interesting, if someone uses a path that I have sent them, I receive a fuel bonus that allows me to make more trips. So, do I share information? How broadly? I call this a "Social Exploration" game.
