For game development the skills required is creativity , craft, and technique.
Getting idea is the important requirement into game development.
Game design process is followed by concept, goal, plan, specification, code, test.

Two steps in Game design process:Step1: Build the concept
1.Get an idea2.Build the game concept 3.Creat a goal4.Creat an emotional experience for the
player.Step 2: Creating the game specification 1.Write the design document
2.Build the prototype3.Chose and appropriate lifecycle model
6/1/2014 5Prepared by Pawar R.B. Gharda Institute of Technology
Getting an idea: Ideas come from dreams and inspiration Programmer should come with unique idea There is brief description What the game should
be written. This should measured in originality, potential
audience(all age group, specific group, only girls and only boys)
Final idea are check and the concept is created.

Game concept: Game is good if player win by doing unexpected
things. The game should have action(use many keys) Adventure (story) Puzzle(analytical thinking) Educational(learning by doing ) Games likes movies combine different feature. Adventure game combine action and puzzle
6/1/2014 7Prepared by Pawar R.B. Gharda Institute of Technology
Difference between movies and games Require input from user Player make decision in game Game some time have no ending, one ending and
multiple ending but movies have predetermine ending.
Game has rule and goals, players, objects, physics, sound, speech and emotion.

Point scoring game having no visible objectiveRacing and conquest type game having visible
objective1.In racing the player knows his/her position,
compare with opponent at any time2.In RPG pointes earned spend on improving the
attribute3. In strategy games, gather resource.4.In adventure games, collect items are used to
solve the something's

Score: ◦ player expect more from game experience than score. ◦ Fighting racing and sports
Moves:◦ controlling virtual athletes' in sports and vehicle in racing
required a steady practice. Explore levels: ◦ Hide the some of the levels, move through the levels
realize the hidden area, ◦ eg. Racing game having additional cars.

The concept put dawn on the paper This will generate the outline and sketch of game
design This will help to move ahead or give up This stage technical constraint are not require only
unique feature take into account. Description of game working is given and result is
committed.
6/1/2014 14Prepared by Pawar R.B. Gharda Institute of Technology
Feature based description easy to understand Feature comes into account from rules Rule changes when detailed the program Reason for changes is the diff. rule interact with
each other.

1.Vital feature(integral feature): This make the game work properly. In football game formation is selected first and the choice of
player made accordingly.2.Chrome feature:
Some feature not effect on the game but increase the enjoyment.
Story, look and feel of the game. Example: player choose the stadium.
3. Gameplay substitute: o Some features does not affect the game but provide lot of
choices to the player. o Ex: player can chose one on one with the computer or
multiplayer mode in LAN.
6/1/2014 16Prepared by Pawar R.B. Gharda Institute of Technology
1.Explain the developer how the game works
2. Provide the vision statement through out
development
3. Identify the feature that are chrome or integral

Initial stage rule should be guess Then more and more rule are added and new
rules is interact with old one and changes made, finally they became a hole.
Rules provide the different features One unit is affected then, affect all other unit
6/1/2014 19Prepared by Pawar R.B. Gharda Institute of Technology
Level design affect the core gameplay. Low level provide the more watching than playing Story oriented game provide more narrative character
so that user involve into game with lot of interest. Level should not be use to create deficiencies into
game. Accurate specification is given to level designer who
understand the rules Primary goal of the game design create interest in
reader and convey the design aspect without ambiguity.
Interest should be from start to end.
6/1/2014 20Prepared by Pawar R.B. Gharda Institute of Technology
Detailed game description: Basic concept: ◦ The idea should be informative and interesting
Background story:◦ This is necessary for adventure kind of game and not puzzle kind of
game Objective:◦ Reader should have clear idea of gameplay and provide more
detailed as possible in design documents
6/1/2014 21Prepared by Pawar R.B. Gharda Institute of Technology
Game play: ◦ Working of game from beginning to end, title screen
and option screen should be displayed, computerized opponent should be provided by Artificial Inteliggence, result of particular option should be known to player, information provide by help option window.

Dominated strategy: The choice witch is not using in circumstance is called dominated strategy
Dominant strategy: The choice witch is use in circumstance is called dominated strategy
Near dominant strategy are used in certain circumstances where above not work
It is widely use by the player Eg of near dominant strategy are given by asking
following question: What is the most common feature? Is the facility use only once then how much developing
time required? How much special efforts are needed to create interface
