Bloodstained has no reason to be a $30-$40M game and I seriously doubt that's what it will cost to develop.
I'd much rather see an independent dev start off small but actually own their games instead of instantly giving up their IP rights.
Including marketing?
Yeah, that's what it'll cost.
Reminder that AA is still 20 people working for 3 years, which at a cost of 8k/month, is at least 6m in just development, without the outsourcing that'll surely happen for various things.
And honestly, i don't think it's 20 people working bloodstained, and i don't think the cost per employee is 8k/month when you start pulling up veterans and legends.
Professional work doesn't come cheap.
