Some thoughts about victory conditions:
Diplomatic
I think this will be the easiest goal (not that any will be easy

)
Ten Deity AIs at the standard map size research rate will drive tech to Fission at a respectable pace even without our help, so any Diplomatic victory should be at a date early enough to get a good score.
Depending on the size of our starting land mass, it could work well for a good score to take out all local Civs, build up that land for happiness, and work toward the UN vote.
A Diplomatic goal could also be the way to shoot for the highest score. Especially if there are some scientific AIs - the research rate could be made very fast indeed.
The main things for the Diplomatic victory of course are:
* Be caught up enough in tech to get Fission before a rival builds the UN.
* Have a prebuild or a leader ready for building the UN.
* Ensure that most of the remaining Civs like you more than they like each other. (And therefore it makes sense to try to completely take out any Civ which you start taking out.)
* [Edit, added this:] An important part of keeping their favor it to avoid breaking many deals and avoid razing many cities of any Civ.
Culture 100K
I think this one is likely to be a bit difficult. It works best when rapid expansion is possible and that's unlikely at Deity. It also depends on whether our starting land mass is large enough for all the towns required. And if not combined with some conquest, Culture 100K can be made harder at Deity by AIs pushing the 50K culture mark.
Domination
Hard to guess, the difficulty of this will of course be affected by geography. E.g. whether our starting land mass is large enough in itself to trigger Domination.
Space
This can be difficult at Deity unless you've gained a clear upper hand over the remaining Civs. If you are not ahead in production and tech this victory can slip away.
Conquest
I suspect this will be a difficult goal on this map because Cracker has designated it as the Predator class goal. (One more reason for us to guess that the map will have land masses separated by ocean - I doubt Cracker would have designated Conquest on a Pangaea map. It even makes me wonder if we may encounter something something special which could make conquest of the last rival more difficult.)
Culture 20K
A difficult goal at Deity, especially if you want a high score. It will be hard to build early wonders and hard to get early leaders, both of which are very desirable for this goal.
Histographic
This would be a milked game for sure at Deity. Hard to reach 2050 without an AI winning unless you have them subdued. So the considerations for it are same as for Conquest I think, except that the score of a late Conquest might be increased by good milking.
I'm not sure yet which goal I'll go for, am considering Diplomatic (shooting for score) and Conquest (to be a Predator

)
