I lost interest in Uncharted after an hour. I never found the auto-platforming fun to watch. The "rubbings" were never enjoyable for me as well.
I found that I only enjoyed the shooting parts, and even those weren't as enjoyable for me as Unit 13
I can see how it could get boring after awhile. I'm just playing it a chapter or so a day. I'm fine with the rubbing and archaeology segments.
