Seriously? Did you sleep through the part of history class which touched on the Inquisitions? There were four distinct periods of Inquisition, you know (Medieval Inquisition, Spanish Inquisition*, Portuguese Inquisition & the Roman Inquisition)
Were you skipping school the week they covered the Crusades? Not "a" Crusade, but The Crusades. With an 'S' at the end. As in, it wasn't just against the Muslims. There were Crusades against the Eastern Orthodox Church (Christians), the Russian Orthodox Church (Christians), Jews, the Pagans, the Cathars (Christians), the Waldensians (Christians), and the Hussites (Christians). Oh, and the Mongols the Prussians and the Balts. If I left any groups out, my apologies, but I hope you get the point that at various times, the Christian Church has been "quite hostile to others", which is a definite understatement.
Did you happen to be sick the days they covered Iconoclasm? It occurred in the Eastern, Western and Protestant Churches and much of it was bloody. People are funny that way, when you forcefully destroy their churches and tools of worship.
Did you skip over the Dissolution of the Monasteries? Monks were slaughtered wholesale.
Do the Acts of Supremacy ring a bell? Embrace the C 0f E or face treason charges and all that goes with them?
Did you miss the part about why people came to America to start with? Hint: it wasn't because the cable TV was better.
Did you miss out on the Mormon Wars? I know I'm missing more than I've mentioned, but you get the idea.
As a Catholic Christian, I know that there is no benefit and every harm in not recognizing the crimes of the past. Never whitewash it. Never gloss over it. I didn't take part in these acts. The only way I can be culpable is if I deny them or fail to learn from them.
Denying sin is sinful. Denying history is not an option.
As for this video game, I have no idea if it is worth playing or not, but wouldn't base my decision on how historically accurate it is. If it doesn't have Mario, talking animals from Japan (街へ行こうよ どうぶつの森, Machi e ikō yo: Dōbutsu no mor), or a Scrabble board, I probably don't play it.
