The Endless Forest

The Endless Forest is an MMORPG for Windows where the player is a deer in a forest without goals or the ability to chat. Unique pictograms above registered deer's heads help to identify each individual. Players communicate with each other through sounds and body language. And that's all there is to it. You start the game as a fawn and play as one for 30 days before you mature into a stag. The entire time you run around in an endless forest as a deer, rubbing against trees, braying/mooing, and emoting to other players. You can also cast "forest magic" on each other, which changes pelts, masks, and antlers.

The creators (also known for The Path) get a lot of feedback for the through the official forums, though it only gets any major updates maybe once a year. The community is very dedicated to the game, even going so far as to create in-game legends such as the Deermuda Triangle, a triangle formation of three glitched (duplicated) rocks in which strange things are supposed to happen.

And did we mention that all the deer have human faces?

This series provides examples of:

 * Action Bar
 * Alternate Animal Affection: Deer can affectionately nuzzle each other.
 * Amazing Technicolor Wildlife: The pelts your deer can wear come in many colors. From peacock, to bluejay, to bright red and more.
 * Amplified Animal Aptitude
 * Animal Gender Bender: For those who roleplay and insist on playing as does there is a set of antlers called "Doe Antlers," which are little nubs. All the playable deer are still male, though.

 * Attract Mode: When you make your deer lie down and leave the mouse idle for a few minutes, the game begins to pan around the forest. See Scenery Porn.

 * Bug Buzz: One of the ambient forest sounds.
 * Cool Mask: Many.
 * Cute but Cacophonic: The fawns are cute, but their call is just as loud as the adult deer. Something Awful once used this to their advantage during a long-ago raid on the game. Thanks this, the creators made it so the call gets quieter the more you use it consecutively.
