I think the best example is the PlayStation 2 being discontinued in 2013, as well the PlayStation 1 in 2006
Which claimants are you thinking of? I know the Ottoman Empire and the Russian Empire both claimed to be continuations of the Roman Empire. I don’t think Italy ever claimed to be the new Rome, somewhat ironically, and I think Germany and France had stopped claiming to be Rome as well.
The House of Hohenzollern in Germany. The Habsburgs formally gave up their claim in order to create the Austro-Hungarian alliance/Empire, but they had asserted it less than a generation prior and also claimed their Empire status on that back of it. And in the Ottoman Empire the lineage of Mehmed, including Mehmed V during WWI, claimed to be the continuation of the Byzantine / Eastern Roman Empire.
