Gods realm, how do you get out? Achieve Nibbana in this realm? It is stated that Buddha said that it is more difficult to achieve nibbana in this realm than in the human realm (due to absence of suffering).

Imagine, that one of these gods, has realized that in fact he is "stuck" there and want to achieve nibbana and get out, even more, he created a whole reality where he "lives" similar to the human realm.
This god did this because experiencing suffering, (even in this "simulation"), it will be easier to look for the exit out of samsara.

Imagine that this god realizes that he's created all that, 
what should be the next steps for those kind of gods, (which actions or intentions), to follow Dharma and finally exit the samsara?

Should he assume a "human form" just to follow Dharma or should he do it "from" the same "gods realm" "perception" ?

Sorry if the question is too "fictious" or not understandable, let me know if you need more clarification.

thanks.
From the perspective of the old Pali scriptures, I am not aware of anywhere that states: "It is more difficult to achieve nibbana in the a godly realm than in the human realm". 

For example, AN 4.123 describes Nirvana ("unbound") in the god realms. 

I think the answer to this common view is based in the type of 'godly' realm. 

A most common godly realm in the Pali scriptures are higher meditation states (jhana), as described in AN 4.123. 

However, there are godly realms that equate to luxurious wealthy lifestyles of sensual pleasures (e.g. MN 37). It is possibly this godly realm called The Sensuous World (kama-loka) that makes it difficult to achieve Nibbana.
