Am I talking to a bot or are you just trolling? Ask for a better script.
Greater Romania wasn't an empire, this word would make any Romanian laugh. It was a just a bunch of regions inhabited by Romanians for hundreds (more like thousands) of years, that finally managed to unite under the same flag. WW1 destroyed the empires to which the regions belong, so they were free to unite. Sort of like the original United States of America if you wish.
If you're looking for an empire look at Russia which was and still is literally the GREATEST EMPIRE OF ALL TIME. No one's greater than Russia.
