God you're persistent.
The bolded bit is false, never said that. For a lot of people MGS will be a 6-8 hour game (a quick Google pulls up loads of examples), for others it won't be. As one of the people that beat it in a few days I thought it was worth the money, unlike gamespot, who I remember being one of the sites slating the length of it at the time.
I remember hearing people talk about the length and thinking to myself 'meh, it was fine for me'. That's the extent of my point, how long this specific game took for you or anyone else to complete, is neither here nor there to me. A well done short game is ok by me.
Would it help you if I used a different game in my post? Ok, pretend I did then.....
