I selected to alternate them, which seemed closest to the current method, although the AI always has a bonus, and sometimes the Human has a penalty.
Here's the quote describing Predator level in the GOTM35 web page:
Players who choose to play in the Predator class game must overcome an extra set of obstacles built into their game to provide an extra level of challenge. The intent of these changes is to raise the difficulty without altering strategic play progress from that which you would see for comparison in the conquest class and open class games.
Players who might be interested in playing the Predator class game could be those players who have participated in the Elite or Leader divisions of the Medal Play Series or players who just want an extra level of excitement or challenge.
For the purposes of global ranking and comparison to all other GOTM scores, the Predator class game scores in the QSC and GOTM results do not receive any compensating scoring bonus for the added elements of challenge.
So, with respect to what Predator IS :
- it is NOT a method to equalize players
- it IS designed to compare to the other classes, so it shouldn't modify the overall game play progress; therefore it can't be too much of a change
- it IS designed to appeal to Elite players, or to those who want an extra challenge
I can guarantee you that if you eliminate Predator level, you will still see the same names at the top each month.
Making Predator level really, really difficult makes any comparison between levels impossible, and given a choice, top players wouldn't choose Predator. IMO, removing the Expansionistic Trait for the Zulu in GOTM34 was cute and interesting, but dramatically changed the game play so implementing that 'challenge' violated the 'raise the difficulty without altering strategic play progress' intention. Removing the starting Worker in GOTM30 is more of an added Delay than a change to game stategy.
I consider myself an Elite player (at least in my own mind

) and except for the 1st month it was implemented (Deity Level Spain, Gotm20), have always played Predator by default (it is a matter of Pride!) I find it a bit disturbing that Top Players are choosing between Open or Predator for game advantage. I have no problem if an Open level player chooses to play Predator of course.
Requiring players who do well to play Predator level may result in losing their involvement which can't be a good thing. Really making Predator level hard would drive people from it; you might as well eliminate it, unless it became a separate award category. You might provide some recognition to consistent Predator play, but that is obvious by reviewing the Results tables.
So I'd pretty much keep things the same.
