I'd say they're pretty darn close in value so if condition is equal between the 2 than yes, pretty much 1 for 1. I actually just had these 2 games sitting side by side in my collection and needed to sell 1 of them. Both "like new" condition and I listed them each for 4800. Sold TSPP first for 4500 so I'm happily keeping POTC. I actually prefer POTC even though it doesn't have as deep of a rule set as TSPP. It just has better sound, more fun shots, and is visually a gorgeous game. Just my preference.
