This post is dedicated to the memory of John Roy, lead environment artist on Star Wars Galaxies. Help out his family here.

 

Corellia0023Let’s do some math. Let’s say that you need to have a pretty big world: sixteen kilometers on a side, and made out of tiles.

A tile needs to know what texture it is. That’s one byte. Not much, right? You only get 256 tiles on a planet, though, which isn’t a lot.

But wait, we can add some variety there, by putting in some colors. We’re in 3d, right, so we can tint the tiles slightly and get variation. It’s normally three bytes to apply a color, but let’s instead just say that each planet has a fixed list of colors, and you can have 256 of them, and that way each tile can look up into a list of colors and we only need one byte.

Oh, and it’s a 3d game heightfield, so we need to know what the elevation of the tile is! We’ll just say that there are only 256 levels of height, and that way we can keep it at a nice conservative three bytes per tile.

Corellia0004That’s good, because we need a lot of tiles. They’re one meter on a side. So that means that for a planet we need 16,384 just to make one edge. We need 16,384×16,384 to lay down the whole world.

That’s 268,435,456 bytes for this world. Of course, we need ten planets, not one. So, that’s more like 2,684,354,560 bytes. Nobody uses bytes, so that’s 2,621,440k. 2,048mb. 2.56 gigabytes, uncompressed.

That’s… not going to fit on a CD. I mean, that doesn’t include any art yet.

DVD drives weren’t yet widespread in 2003. In fact, taking up 2.5 gigs of space just for maps was unheard of.

The solution to that problem didn’t just let us ship Star Wars Galaxies, it also unlocked everything from player housing to crafting to giant Imperial vs Rebel battles.

Before you read any farther, you should know that Sony Online actually patented some of the technology that I am going to describe. If you are someone who should not be reading technology patents, you should stop now.

Continuing here with the questions that were sent in by Jason Yates! Yesterday it was the TEF system… today it’s Jedi! Some of this stuff has been told before, but it’s actually kind of hard to find it all in one continuous tale. I have to preface this with a huge huge disclaimer, though: it’s been fifteen years since this particular story started, and a dozen since it ended. My memory may well be faulty on many details.

#2 What were the thoughts on Jedi and why were such drastic changes made in patch 9 to the entire system?

Well, my opinion is Jedi are evil. Heh.

You see, Jedi are an immense attractant to players, readers, viewers. As a kid, I too waved around plastic lightsabers (we kept bending them as we struck one another, I am pretty sure my mom got really sick of buying new ones). Who can resist the fantasy of having this awesome sword, effectively magical powers — mind control, telekinesis, telepathy, and more — and of course, the classic Hero’s Journey? I mean, it’s basically an ideal play scenario.

I was sent this list of Star Wars: Galaxies questions by Jason Yates; he had seen this video interview, and didn’t know enough Spanish to be able to follow the answers. I posted up an English translation of the transcript here, but really, the interview didn’t much overlap with the questions he had.

Is there the possibility of you ever giving a question/answer session in relation to SWG, your views on the game development and direction, aspects of the game you felt worked, worked well, didn’t work at all? Like many, I have so many questions about your involvement with SWG and will likely never get all the answers I would enjoy hearing, but it never hurts to ask. ^_^

Well, honestly, for me it has been fifteen years since I started work on SWG, and twelve since I stopped. So a lot of these questions have either been answered before, or I outright don’t know or remember the answers! So I will give it a try. But the first answer turned out to be so damn long that it’s all I have time for today.

Here is the full video of my talk at EVA13, entitled “El mundo de sistemas” (the world of systems). It’s in Spanish, and it’s an hour and a half long!

Sorry, no translated subtitles or anything. The talk starts out talking about systems and games, how there are many sorts of games but that a large proportion of them have what I call ludic systems underlying them. I talked a little bit about what some of the implications of systems are, how we learn from them and what sort of lessons they teach. And, of course, also how flaws in systems (or even emergent properties) can cause systems to really run amok, or enable players to really break everything.

That then leads to some anecdotes and postmortem thoughts from Ultima Online and Star Wars Galaxies. Most of these are probably ones that many of you have heard about before:

Here are the slides for my talk at EVA ’13 in Buenos Aires, Argentina, last week. They are in Spanish, of course.

If I had to summarize the talk, I would say that it covered a lot of the same sort of ground I have touched on before in terms of the ways in which games teach systems thinking. I open with some discussion of the wide range of stuff that we call “games” — something that is also discussed in the GDCNext talk I am posting shortly. I talk about what a ludic structure looks like (something that folks who read the blog will probably find familiar), and the way in which ludic structures arise naturally in the world, and thereby are playable even though they are not designed games.

And then I move into anecdotes on exploits and loopholes and other ways in which we didn’t grasp everything about the systems we ourselves had designed, in games such as Ultima Online and Star Wars Galaxies. The talk ends on speculation on what we’re doing to the world, as we create systems that break outside of games. Are we the most qualified to do this? We might be.

It likely loses a lot without the actual speech, compared to most of my slideshows, but hopefully the video will go up at some point. In the meantime, the PDF is here.
