While in the game industry we don't face these sorts of moral decisions, we do have our own cloning problem. It seems you can hardly turn around without another first person shooter or real time strategy game popping up theses days. And even the clones breed sequels. Game development today, for any significant title, is a significant undertaking. Development teams can be quite large when you consider that programmers, artists, musicians, designers, testers, level builders, 3D modellers, and even more specialty disciplines are often required.
Games are also more elaborate than ever before.
We've come to expect flashy graphics, original sound and music, long campaigns, and depth of play. Complex games are harder to develop and test, especially with multiplayer thrown into the mix. This protracts the development cycles and again increases the cost to develop a game. There is manufacturing, marketing, etc. Add to this that the developer only gets a small fraction of the revenue from sales.
