So I just posted a VERY negative comment about RE6.
Now, on a more thoughtful note... I wonder what we would have made of this game if it did not have the RE name and characters.
Here are a couple of impressions:
1) It would have received a review score around 6.5 by GameSpot, and similar scores by other reviewers (if you look it up, it has quite a few positive reviews from other reviewers). 4.5 IS a bit low, but I commend GameSpot for shining the spotlight (see what I did there?) on how far this game has drifted from its roots.
2) It would not have produced all these mixed reactions from the gamer community - people would largely have agreed that it's a straigtforward and entertaining shooter, but nothing more. "Okay for a weekend rental".
3) It would have shown medium sales and never received a sequel.
