Principate
Saint Titanfall
Bloodborne did extremely well for a new IP early on in PS4's lifespan though. You can't tell me that's not a successful venture for From and Sony just because it sold less than the 3rd entry in a popular multiplatform IP.
If it was sold multiplatform I assure you it would have sold better. It's sales on the steam alone would ensure it since Dark souls is a million seller on steam. Bloodborne is way too similar to Dark souls for the fact it's a new IP would be a substantial hindrance.
