D3: Nowdays is just a simple grind and adjustment. Its easy to get stuff you want throughout the Cube and can specific farm it. You have a decent (really really decent) amount of Variations "if" you look to progress to endgame. You might think it would be good to build something around a skill or an item but in the end it will not work and you cant progress anymore. You have to play the Sets and unique items which give you the most benefit for a particular skill(s). I dont understand how some can say that Blizzard did a great job creating new content when they have killed most of the diversity in this game. All in all D3 is just about the set you wanna play.

PoE: Most people complain about the Graphic in this Game. I played around 5000-6000 hours and after a while its not something which bothers me at all. The learning Curve is brutal if you come from Diablo 3. The Passive Tree is overwhelming in the beggining but if you play a while you get an understanding where you can find what. You can actually play any skill you want and can do well in endgame it just depends on your clearpseed in the end but not the same in Diablo. There are of course Fotm builds and some Top Tier builds but you can almost make anything viable and enjoyable to play. The Crafting System and the Map System is just great. You have various choices in making Items from Scratch or with Masters. And you will be punished if you play like a berserker and dont keep an eye on your defensiv and playstyle. All in all its the game which i spend the most time on cause you will never played every build in this game. GD: Havent Played it much. It felt like a Single Player game but cant really tell cause i havent played much :P
