"game" or "sim"

[Chivas]

They are all games, and the best ones have options to make them feel more or less realistic to suit different peoples sense of gameplay.

Unfortunately these sims have become too complex, expensive, and time consuming. Developers who can afford to even think about developing them wouldn't bother when there is so much more monies to be made with less complex type sims. The only people willing to develope complex combat flight sims are enthusiasts who are eventually forced to release unfinished products to stay solvent long enough to finish them.
