So what's your ideal length for a $60 "triple a" retail game?

[S.Peelman]

That seriously depends on the game or it's genre.

For example, Star Wars Knights of the Old Republic lasts me 50-60 hours to do just about everything. The game is so great however and doesn't get tedious in any way, that to me this is actually still 50-60 hours too short.

However, in a stage based or linear story based game, things can sometimes get too long. Even a more adventure based one, like Luigi's Mansion, which I absolutely loved, could have made due with 10 hours less than the 30 I put into the game to complete it when it got repetitive.

Then, open ended games like SimCity or arcade style games like Star Fox are something else entirely of course.

In short, there's no way I can answer this.
