Those who are comparing these two (uncharted and tomb raider) started gaming after 2006. Probably with Xbox 360. Ask veterans.
Uncharted 4 looks like it took cue from old Indians Jones games, specifically "Indiana Jones and Emperors Tomb". They were excellent. People who are saying tomb raider similarity because of that wall climbing thingy. Lol.
BTW tomb raider is a franchise that always copied other big games. Indiana Jones served as an inspiration. But tomb raider legend was a "copy / paste" from "Prince of persia two thrones".
But nothing will change. Why? Because most of the people who are comparing have no idea what I am talking about and started gaming late.
