No, not at all. Throughout the development of Habeamus, we always checked back with theologists for advice. Our goal is to have an enjoyable game in a very compelling setting. Yes we do use the catholic church in 1492 in our setting, and it is highly corrupt. Luckily this corruption has been taken care of very soon after Alexander VI, when his second successor Julius II issued a bull that punished simony (trading offices, relics, or money for votes).
So we worked hard to stick to a specific time interval of the catholic church that has been described in many sources.
If you are interested in more of the background and context of the papal conclave 1492, I can only recommend our rewards including the art booklet, where we describe more of the actual history and art styles around this event.
