Heavy rain Better than Indigo prophecy according to MC

[SpartanFX]

i was just browsing and noticed that Quantic dreams last game ,indigo prophecy,was rated 83 on metacritics while heavy rain is rated at 89 on metacritics.

 

so is it safe to assume that QD has improved upon their own formula?

 

 

P.S. I haven't played HR yet .
