"Short" is not necessarily a bad thing ...
In the late years of Rare on the N64 many of their games forced to to go through the exact same content multiple times so they could brag about how their game was a "60 Hour game" ... Jet Force Gemini was one of my favourite games on the N64 and after its first ending (at roughly 20 hours) it would have been a classic game, the second ending took a lot longer to get to because they forced you to go through all of the previous levels as each of the three characters and then they added a similar number of new levels which you had to complete with all three characters.
