Game developers
can use the game engine to create casual video games,
first and third person shooters, role playing games, racing simulations
and more. The game engine can be used to make both 2D games and 3D
games. Beginning game developers will only need basic knowledge
of
game design and programming to create rich and complex game models with
photo realistic textures to add detail to the graphics of the video
game. Today's games need more than good looking low polygon game
models. Use normal maps and photo realistic textures to create
high
quality game models.
