You are seriously low-balling for Spiderman I think. The game is going to be huge.7 million is huge! Game looks great but Insomniac has not made a mega seller in a long time, maybe ever. Spiderman IP will bump it up but imo it's too early to really know if this will be the studio's big break (similar to Horizon for Guerilla) or if it'll just sell off the IP alone.
If anything I'd bet I'm vastly over predicting GOW.
