The aim of Platinum - difficult and popular games.
Now I am not saying that Fable 2 is easy, its just RELATIVELY easier than most games purely on the fact that it hasnt even been 2 weeks since launch, and close to 5 people have the full 1000G. I would not be surprised if there are 10 more by the end of this year. Since I started this league, I have never seen such a quick turnaround in one game alone.
However, I do admit that I have dropped the ball on researching the Achievements with SO many games out now. A Platinum game should be decided and not revoked (unless its an old game which no one plays anymore) which is what Im aiming for.
I think the demand for Fable 2 is increasing so I might yield to popular opinion, let me keep on reading what people think.
In regards to Oblivion, the Platinum is awarded because of time-based difficulty. Difficulty is both skill-based and time-based.

The problem with that is CoD4 which is difficult. However, I will indeed switch very old games out with new games.
I also think if the League is to be better, I need help from people to rate Achievement difficulty so that we can decide earlier whether it will be a Platinum.
