Love Demo at GDC

I went to GDC to see a demo of Love and the tools used to create it. Eskil Steenberg is the one-man team behind the game and the tools. I played with the tools the night before, so I was interested in seeing someone who knew what they were doing use them. The tools are something else. The tools are visually compelling, sparse, and bit foreboding owing to their entirely unique interface. Each tool is dedicated to one task, and they all interact real-time via the verse server. In a sense, they are an extension of the Unix philosophy of development with respect to small tools.

For the tools demo, Eskil brought up his game Love, and brought up Loq Airou, which is the 3D modeling tool. He approached an object in the game, and he found the geometry for it in Loq Airou. He then moved the object up in Loq Airou and the game showed the object move upward to a levitating position. It looked seamless. There wasn't any noticeable latency between the update in Loq Airou and the game. I expected there to be a beat where they were out of sync, but I didn't see that. He could scale, rotate, or twist the geometry and it was all immediately conveyed in the game. Eskil noted that by having this kind of direct access to the objects that are hosted in the world a host of problems become very easy to address.

After talking about the tools, Eskil talked about the game. He created a post in the game, just an upright post like a lamp post. He placed another post some distance and connected the two posts: A white and black stripped rail appeared hung between the posts, and Eskil jumped on and sled to the other post. This is part of the game's infrastructure. Players can create their own fast-access paths through the world.

Eskil then placed a mine on the ground. It had a built-in radio that he configured it to listen to a frequency and a keyword. He changed his chat to the same frequency. When he said the keyword, the mine created an explosion of colors. Then he showed how to convert that chat action into a button, and clicked it quickly and the mine exploded furiously. (This can be done with any chat action, so group coordinating efforts or things like "help" can be made into a button too.) Neat, I thought, but the next part really astounded me and opened my eyes as to what kind of game he was putting together. He placed a new item on the ground. It was a proximity sensor. He configured it to the same frequency as the mine and to emit the same keyword. Now, when he stepped on the sensor, the mine exploded (from a safe distance). He said that doors, gun turrets, and all manner of objects in Love have radios. Just think, one could build Star Trek-like doors in this game (a door with two proximity sensors would do it).

Next thing to show off was the mutable environments. On a small bridge, he grabbed the floor and extended one block of it upward, raising a pillar. He did this across the bridge, effectively making a wall. Then he cut into the wall, leaving a doorway. This reminded me of MUDs which are one of the few games that offered mutable environments, and for MUDs the task was easier because it was all text. Next Eskil walked up to a cliff face. Using the same tool he demoed to create the door, he just started cutting into the mountain. I immediately thought, this is Dwarf Fortress but in 3D with guns! I expect to see a lot of creativity expressed in this game.

I wish I had asked to see what the avatars look like. There is a screenshot that shows what may be a player character, but I am definitely excited by the prospect of getting to try Love. One of the things that Eskil emphasizes a lot is the creation of stories by the players rather than by the game developers, which I think is laudable. I don't know exactly how he intends to create that kind of social storytelling, but he will be limiting the servers to about 200 people, which is I think a good call. It may allow for social norms to be operative, and hopefully it will be small enough that the social circles of people will overlap. Thinking on it, Leeroy Jenkins is a great piece of player storytelling, and it's a rich piece of media. I hope that the players are given some storytelling tools that are richer than a chat client. Maybe a camera or even a video camera would be a welcome edition to multiplayer games (i.e., in game cameras and video cameras that capture what the player sees, not a webcam or anything). Before the raid on an AI's settlement, everybody turns on their video cameras in case there is a good story to share afterward.


  1. Extremely exciting game and tools. Eskil's work is inspiring from many different standpoints. It really hits the spot; for he is creating what my dreams have imagined of the true cyberspace potentials...

    Did he mention anything about a release of the game or tools? His site is so confusing and I can't really understand if its in beta or what?

  2. Hello Jason,

    I too take heart in the idea that Eskil is trying to make the one-person game development viable for bigger games.

    The tools have been released. I would consider them in a state of beta though. I don't know who's using them currently. They are doing some things with them at They have a cube scene tutorial. I was considering trying to do a screencast of it, but the last step doesn't work on Mac OS X.

    Eskil didn't mention any kind of release timeframe for Love, but he did say that the engine was complete.

  3. This demo was great but the end result was a bit disappointing. They placed all the good things in demo and nothing was left to this final release.
