I've been reading through some old threads and noticed that talk about replayability of AIF games was pretty common. Most of the talk though didn't actually go into what made a game good to play multiple times, thus an open thread.
First: I don't want to imply by any means that a game has to be replayable to be 'good'. A good game might be great for just one play through, that shouldn't necessarily detract from the quality. I think though that many authors design for replayability for more of an emotional payoff (I believe I've seen both Palmer and BBBen discuss this). It takes a long time to design a game and it would feel better if it got multiple plays instead of just a single go.
Here are the questions:
In general, what elements makes you want to go back and replay a game? Quality, multiple paths, hidden scenes, something else?
Do you go back and replay games long after your initial play through?
What AIF game(s) have you played the most times and why?
