I noticed a huge double standard here. If it has SEGA on the box, lower the score 3 points. I guess I might agree, I haven't played it so I will see soon.
Don't forget that SEGA hasn't used IGN to promote Alien: Isolation through any of their ads on the website, it shows by them picking the reviewer they did too (He's a big Halo fan and in general FPS.)
Not sure if this is relevant but I was interested in seeing how well Alien was doing, the only information I have access to though is the Amazon charts and Stream charts.
Steam
10. Alien: Isolation
(There was a deluxe edition that included the season pass but that's dropped out of the charts or Steam has combined the SKUs into one.)

Two things to note, firstly the UK has multiple SKUs see it might, if it ever gets there, take Alien: Isolation a little while longer to get in the top 100 best selling in video games for Amazon. Second I'm really surprised at how much more Alien there is in the UK charts than the US one and the massive difference in positions too heh.
Though I think it might be safe to assume this game might breeze past SEGA's 2 million+ expectations... I just hope if it does The Creative Assembly are allowed to make an original IP (Or if they want to work on Predator next I'm totally down with that idea too! : D)
