A world is randomly generated each game, with player input on land size, the strength of magic, game difficulty, and other features.

Game characters can be given autonomous tasks and these are then executed independently by the game engine, without further need of player input.

The game also allows for simulated matches with no player input.

Interactive fiction features two distinct modes of writing: the player input and the game output.

As described above, player input is expected to be in simple command form (imperative sentences).

These games often do not use very much player input, as the plot is unchangeable.

Many modules require player input to be useful.

The player input the weapons and leaders directly into the game rather than using counters as in the board game.

How to distribute player compensation could be negotiated with player input.

There's no player input at all, of course, and it's useless without a VCR, but ideal for someone with everything.
