Don't know if I've ever seen an Opencritic-only aggregate score thread. Congrats to you on being different. :) 86 on Metacritic by the way.
Metacritic varies wildly right now on a per platform basis. So I chose to go with Opencritic. It's not like the game is going to run significantly better on any one platform. It's a Sega game, and they are using the same engine as the PS3 original.
