Can someone answer a question for me?
I've beaten the game once on the 360. I'm really looking forward to a more in depth play this time on my PS4. One thing that confuses me though is the motivation to keep playing for hundreds, and in some cases thousands, of hours. Whenever I replay games, I replay them in order to beat them on a harder difficulty. That, in and of itself, is the reward.
Clearly this is isn't the case with this game. It seems like the loot is the main draw. And then there's Adventure mode, which seems like it has a lot of appeal to most people.
So it's not just jumping back in on harder difficulties with your beefed up character that is the motivation? What's the point in outfitting yourself with high end equipment then?
The higher difficulties are the point. Working up to Torment VI (the highest difficulty tier) and being able to survive is challenge in of itself.
Unlike D3 on PS3/360 which difficulty was you simply running through Normal, Nightmare, Hell, Inferno story modes over and over. By the time you got 60 midway through Nightmare, it was pointless because by then you should be running Inferno. Which is why they did away with all of this.
When D3 v2.0 patch came out they completely revised the difficulty mechanics and altered the Paragon leveling system.
Getting to 70 by playing the story segment game is easy enough with a few Adventure Mode runs afterwards. This can be considered basically a tutorial for endgame when you need to find the right gear, increase your Paragon Levels (Levels beyond the 70 cap) and be appropriately fitted to handle Torment levels of difficulty.
Normal, Hard, Expert and Master you probably gradually change between you feel the challenge isn't enough when playing the game.
Torment 1 through 6 is when things get interesting.
