Jürgen Hubert commented on Castle Falkenstein by Michael Alyn Pondsmith
Most #Steampunk #ttrpg settings have the problem that they tend to gloss over the evils of Imperialism and Colonialism. #CastleFalkenstein fares better than most, since it portrays Imperialism as something that ought to be opposed more often than not. It is perhaps unfortunate that the point-of-view protagonist is a white male 20th century American, but it should not be too hard to include other characters.

Yes, there was a #GURPS version published for it (which I recommend as a generic "World Guide" even if you don't use the rules, as well as the supplement Castle Falkenstein - The Ottoman Empire), but they'd need to be updated for 4E...
