So UC2 is obviously superior to UDF, but not in every way. Here are the things I thought were better-
- The Enemies. To me it seemed like there were more enemy variations, different shirts, clothes, faces etc.
- Story in General. I much prefered the story in UDF and I liked the villains more.
- Realism. So, yes, it is a video game but in a game like Uncharted yetis just didn't work (UC2) The descendants were more believable.
I have and played all three. Too bad I haven't played the one for Vita (I am not huge on portables so I tend to avoid games meant for it.) Perhaps if I actually owned a Vita I would be more inclined to buy it.
Can proudly say that I played and beat UC1 before UC2 came out......sure, only a couple months before, but still.
I would tell people to not only play UC1, but to play the games in order.
