To be honest, I believe it was you that brouht in the term "the serious route", and from your post I guessed you by that meant more like IV than the previous installations (I have not played any of the previous), regarding "extra activities".
And what I mean (and that is strictly a prefference of mine) is I do not allways enjoy all the "fun features" that are put into games.
I don't really worry myself about the TONE of the game. This can be "serious", "humourous", "fun" or whatever, if I find the game satisfy my definition of "fun".
I only play for relaxation, and I really don't need a game containing lots of annoying and agonizing extra activities.
But this is just me, and I will probably get the game some time a year or two after it is launched anyhow.
Will probably never get a 1000/1000 - I hate mulitplayer achievments.
