Adjusted for inflation which Transformers series was cheapest to produce?

[UnicronusPrime]

Pretty much the title.

I'm watching the first episode of Armada with my son. It looks... Kinda cheap. I mostly want to know where it stands budget wise.

I don’t think we have any information to go on to make an assumption.

Presumably the stuff Hasbro did on its own (G1, BW, BM, Prime, Rescuebots) would have cost more than the Co-productions and/or stuff Takara took the lead on (RiDv1, AEC, Cyberverse, Earthspark)

I feel like Prime was probably the most expensive. Cheapest was likely those Machinima abortions but I can’t point to data to back either assertion up.
