Rank the Franchise
Here's my ranking:
1. Uncharted 2: Among Theives (10/10)
2. Uncharted: Drake's Fortune (10/10)
3. Uncharted 3: Drakes Deception (9.8/10)
4. Uncharted 4: A Theif's End (9.6/10)
5. Uncharted: Golden Abyss (8.2/10)
Ditto. The individual ratings, I'd have to think about. But I would rank them in the very same order as you have.
I do think I'd give A Thief's End a much lower ranking. I think, despite its strengths, it has many, many issues that should have been addressed and fixed before it got to my console. Along with a few issues that couldn't have been fixed, which is more damning. Still, it does have its strengths. Just wish it had been better.
Golden Abyss was actually a neat little game. Its chief limitations were necessitated by the PS Vita.
