How long should a demo run last?
Some weeks ago i released the demo for my game. After some thousand demo-runs i see that the average play time of my demo is 38 minutes. (and also the wishlists start to grow, so the demo is at least not too bad)
"Corridor 13" is an anomaly spotting game and the Demo ends after Corridor 8 / 13. (It was 6 / 13 for the first hundreds of runs, than i changed it, because some players had too much luck with just try and error and finished the demo very fast without even saw anything interesting)
the full game will be about 1.5 or 2.0 hours i think. thats what i expect to achieve when its done. 2.0 would also be good for preventing people to play, end and refund it.
So, is 38 minutes of demo content good? or too much for a game with that limited amount of gameplay? What do you think?
Thinking about that 38 minutes, that may mean that some people just play it a few minutes and others play the demo waaay longer than 38min. But i dont have detailed statistics about that.
