Get Started


Now let's check out another game from a different aspiring designer. - So my game is "Flooded Market." It's a multiplayer strategy game where you're going to enter the cutthroat real estate market of the sinking city of San Francisco. - OK. - Yeah. - Cool. - So you're going to be outbidding other players. You're going to be renting. You're going to be renovating these properties. And all the while, turn by turn, climate change is going to cause the sea level to rise, as it is in our starting screen. - So this is fast global warming. - Yeah. Accelerated global warming. And as it moves up, it's going to transform these properties from their regular selves into pristine, high quality, beachfront property. And then destroy them right afterwards. And so you're trying to catch that wave of inflated prices. And that along with paying off the right politicians will let you-- - So this is multiplayer. - It's multiplayer. Up to 50 players can play in a game. We haven't tested with 50 players. But the system is there to support it. And the notion is that you have all these players creating an economy that you're then going to try to optimize and act inside of. And, ideally, all the player actions are driving the simulation while the simulation drives. - Well, right off the bat, I love your intro screen. - Yeah. - I mean, it looks fun already, just looking at the intro screen. - Yeah. The intro screen is to make that striking first impression. - OK. So let's see the game. - Yeah. Let's get into it. So you're playing. We're going to create a game here. - I like the pitch, by the way. I mean, it's very succinct, concise. And it sounds fun. - Name this Will's Game. So we're going to launch in here. So right now we're going to kind of get the gist, the lay of the land. There's San Francisco, for those who recognize it. WILL WRIGHT: So you have a real map of the real city. GAME DESIGNER: Right. Yeah. We pulled from map data to help get elevations and locations, and also house prices to start off with. WILL WRIGHT: All right. GAME DESIGNER: So we have a house downtown that's worth $1.3 million. It's five stars. WILL WRIGHT: Are these all things for sale? GAME DESIGNER: These are all things for sale. Yeah. - So I have a budget. And I'm choosing how to spend, invest in real estate here. GAME DESIGNER: That's right. Yeah. You have $3.8 million up here. And let's say we could even select this house. We can bid on it. This one, we can take a look at, and say, OK. It's got some nice views. It's got a decent quality. We can upgrade that later if we want. It's kind of getting close to the water. 20% water level. WILL WRIGHT: Yeah. GAME DESIGNER: We can check. Its elevations at 50 meters. The water right now is at 0 meters. But that'll change as soon as the turn ends, which is fast approaching. - So this turn based? - Turn based...

Students give MasterClass an average rating of 4.7 out of 5 stars.

Give a very fundamental understanding of game design. I will listen to this class again and then will start creat games!

A really unique class. I definitely enjoyed learning his process when it comes to game design and development. I hope for more classes in this area!

As the mother of a kid who just finished a BFA in interactive design and game development, this course helped me get up to speed with where she's coming from.

This class is one of the most balanced and thought-provoking treatises of the game industry that I've ever seen. It should be a keynote at GDC :) Thanks to Will for sharing his vast wealth of knowledge with us!

The game looks interesting. The map looks too busy for me and the time aspect needs work on

What a great game M.U.L.E. was. Back in the 80s when graphics and sound were so limited you really had to rely almost entirely on gameplay to make the game and M.U.L.E. was a great example of how a unique concept could be so effective and fun. Of course back in the 80s most game concepts were new so they had the advantage of all being fresh unlike now where so many genres have already been identified and the low hanging fruit of game design already well picked.

Agree. Good pitch! Game idea is nifty too, and the visual aspect will appeal to most folks even if they're not typically sim gamers. Best of luck to the designer(s)!
