Unless I'm missing something...we don't have numbers from the PAL charts, we only know how high it charted, & it charted #1 in nearly every chart in EU, despite BF3 (which was the best selling game in the series).
The only numbers we have are:
- 3.8 million day one shipped.
- 5 million first month (unclear whether shipped or sold).
- ~9 million as of April 2012 (5 months after launch)
- ~800k NPD.
- Double Uncharted 2's first week WW
- UC3 sold 37% higher than UC2 in the UK.
- Triple Uncharted 2 sales in Japan
- Uncharted 2 sold 4.9 million as of 1 month before Uncharted 3's launch.
Those are the only numbers we have.
Let's not forget that The Last of Us sold-through 3.5 million in its first three weeks, & that was a new IP & not an established franchise like Uncharted, & it only sold ~900k on NPD as well, considering UC3 reached every sales milestone far faster than TLOU, it's not that far-fetched to say that it sold 1 million more than TLOU in its first month.
