I actually really enjoy Uncharted 4 more than the other previous games because of the rope swinging alone. It doesn't seem like much, but it really is fun trying to figure out how to get across canyons or cliffsides with the rope swings. There is also a bit more stealth, like hiding in tall grass to silently take out enemies and you can target enemies for your AI partner to take them out for you in some places. The gun fights are still repetative and simple, but yeah, the swinging around is worth whatever the sale price is nowadays.
