Well it has a creator who knows what they are doing who isn't part of the simulation but can guide it and fine tune it's parameters and maybe put a pop up ot two (Bostrom) so yep, it's pretty much there. Unless you try to get round it by saying that's not religion....religion is veneers and handwaving and bombs etc.....but that would be, er, trying to get round it.
'Can guide it' and 'do guide it' are different things, and most religions make some sort of claim to a moral 'sanctity' on the part of the creator, but I guess you could see it as sort of stripped down version of religion... except that I don't see a suggestion of worship in there:
"noun
1. (uncountable) The belief in and worship of a supernatural controlling power, especially a personal god or gods.
2.(countable) A particular system of faith and worship.
3.(uncountable) The way of life committed to by monks and nuns.
4.(countable) Any practice to which someone or some group is seriously devoted.
5.(uncountable, obsolete) Faithfulness to a given principle; conscientiousness."
Wiktionary, which isn't necessarily the best dictionary, but it's reasonable in most instances.
I fail to see the required 'worship' or 'devotion' elements. You might say that there's a 'faithfulness' to the principle, I suppose, if you're arguing in support of it. I see it as a scientific hypothesis more than a religion.
