Religion in Civilization IV

but first…

There are few games that show any flair for simplification. 'Sid Meier’s Civilization' is one; Sid was so brutal in his simplification of history that I sometimes wince at the game's inaccuracies. Yet the result of Sid's design parsimony was one of the greatest computer games of all time.

- Chris Crawford

Religion: Simple is Better… and Safer!• v1.0: Levels (None, Low, Medium, High)• v2.0: Countable (Number of Praying

Hands)• v3.0: Boolean (Either There or Not There)• “Natural Diffusion” vs. Missionaries

Version E – January 2005

Limited Specialists Wonders create Great People Combine Happiness and Luxury Sliders Automated Workers Starting Eras Multi-unit Graphics Unit Flags Subdued Terrain Palette Tile-Based Coastlines Prototype Animated Leader First Main Interface Pass Screens: Tech Tree

Whither AI?

• Not easy to prototype• Traditional testing fails too• Need hard-core fans to analyze• Automated testing helps greatly

And… don’t forget that fun comes first!

Gameplay Graphics Interface

The Civ 4 Development Experience

Gameplay: First Half Graphics: Second Half Interface: Early and Late

But… it’s never too early to work on good Interface Widgets

Art Prototypes

• Different goals from playable prototype• “Functional” concept art• Develop art prototypes outside production

loop• Avoid waiting to see if it’ll work “in-game”

5 vs. 5 melee combat (Standard)

1 vs. 5 melee combat (Extreme Case)

It takes too long to move units…

Do this whenever you can

All new art should have an “in-game” concept image.

The Point

Iterate on fun when it’s cheap

Finish game before production starts

Art must reflect gameplay
