You were also meaning that UC on hardest isn't as difficult as GoW... I can tell you that besides boss fights I could randomly use the same combos on almost all enemies, or just know what works for each, and plan what type of enemies to destroy in order... wasn't nearly as difficult as UC. And of course in a FPS the purpouse is shoot to kill and depending on the case do some stealth. Still the approach itself is very different for each scenario.
Also it isn't only about sponge, is about how much damage you take and the how faster it's for you to get surrounded.
I didn't. I said:
God of War has always had better gameplay than Uncharted. Some consider the older games button mashers, others call it too easy, and it all really depends on what difficulty setting you play. Play on Easy and Normal and it can be played as a button masher and it is easy and play it on Hard and Very Hard and you have to effectively use combos, strategise which weapon you use against which enemy and time your parries and your rolls. It requires great skill to complete a God of War game on Very Hard and you fully realise the depth of the combat system.
You can't keep doing the same combos on the highest difficulty. You have to be thoughtful when fighting waves of enemies, as there are a lot of enemy mixups. Uncharted is a good TPS game but its got little variety in enemy types apart from the last enemies in Uncharted 2 and 3. The hook does give it some more depth in Uncharted 4 and does the better AI but mechanics wise you can't do the amazing acrobatics like in God of War and God of War 3's weapon system puts it close to Devil May Cry 3's combat, you can juggle endlessly and parry nearly every attack but you need skills for that. Uncharted involves aiming and shooting with a trigger and taking cover, and the act of shooting and taking cover require no complex movesets so the skill ceiling isn't high.
