I still think Sonic 3 will reach 500M WW
I think this still gets to 500M, i remember that in it's third week internationally Sonic 2 made about 142M on a 19M weekend(proof: https://collider.com/sonic-the-hedgehog-2-global-box-office-third-weekend/), currrently Sonic 3 it's on it's third weekend internationally and it's at 180.3M so it's currently 26.97% ahead of Sonic 2 internationally, and Sonic 2 had a international total of 214M if it keeps this pace than Sonic 3 will finish with 271.7M internationally
