I just wanted to give some thoughts about the XBox version, as a nearly five year veteran of the PC version.
Summary: It's really nice. Outside of one glaring oversight, it's pretty on-par with the PC version.
I'll try to cover as much as I can below:
The Comparisons:
Performance:
Performance-wise, it's very good. There are minute framerate drops when S gets crazy, but I'm also rocking an 1080 GTX, so it's not a fair comparison. I don't see real slowdown in general play and things look nice. I'm curious what the XBox One X upgrade will do to it. The GGG team were the first team to run an XBox One game at 4K, so my low-tech 1080p TV should rock a solid framerate no matter what gets thrown at it.
Controls:
Smoooooooth. I've read the articles about what they did in consideration for the console, but it's a totally different thing to experience it. Auto-aim for skills is nearly flawless, and any real inaccuracies are generally my fault. The auto-loot preference detection makes looting sometimes even better than the PC! I can drive-by pick up currency reliably. It's a little harder to pick out items you want from a pile of stuff, but adding in Neversink's filter cleared that up a lot. Dual-stick navigation is super nice and the buttons map generally well.
Multiplayer:
It works super well on the XBox. I'd probably have an entirely different opinion if it was on the PS4 instead. It integrates with parties, friends, etc. and naturally fits. Instancing and joining work exactly as they do on the PC
Load Times:
Are equivalent to what you'd expect on the PC, if you were using a spinner.
Luckily, XBox's support external SSDs. With that installed, zoning is near instantaneous, just like on a PC. There is a negligible performance hit because I'm running at SATA speeds on the PC and limited to USB3 speeds on the XBox, but again, it's night-and-day compared to the internal spinner.
The XBox Exclusives:
Trading:
Auction House lite. The XBox version's of the Trading Post is literally a dump of the public stash tabs for all players. As long as you put something in a public stash tab, people can find it. Same as for the PC. However, in-game, you can set the price as an item note for others to figure out what you want.
It's not exactly the same as poe.trade. Like the AH, this interaction is managed in-game. Player X has an Abyssus he wants to sell. Player Y sees it and offers 3 chaos. Player X can reject that offer.
Imagine the smile on my face when, as I was out farming a map, I see flash across the bottom of my screen: "Offer rejected: Too low newb"
You can filter on only online players, there isn't a need to meet anyone anywhere and do a player-to-player trade. It's super convenient (except for one thing, listed as a negative below)
Auto-leveling Gems:
I don't know why the PC version doesn't have this. No more clicking ten times in the upper-right of my screen when I level. When a gem levels, it does it automatically and even displays the stats gain for the gem from level A to level B. It's a super nice touch.
You can disable auto-leveling on a gem-by-gem basis, which you'd obviously do for things like stat creep and CWDT.
The XBox Baddies:
What? It's not perfect?
Expect to see a recurring topic for this section.
I can't read anything!:
Flash back to three years ago, when PoE steadily increased the graphical fidelity of the game without any optimization. The running joke was that the developers must be testing with godly machines and leaving us normal people behind.
Well, the same has to go for the resolution choices for the XBox. The font is horrifically small. I don't know how people new to PoE handle this. I generally skip reading most things because it's too hard. An analogy to this is remembering the first time you hooked up your PC to a TV instead of a monitor. In theory, it should work, but it looks super horrible. Yeah, that.
I can't see anything!:
The XBox viewing area feels super confined. It displays just as much real estate as my PC, but I feel trapped. I can't move around the mini-map to retrace my steps. I have a super hard time navigating around the skill tree. I don't even know how I'm supposed to see things on the Atlas.
Inventory management is a nightmare:
The only times I used to think this is between league seasons, as I merge my league loot into my Standard stash. Now, I think this every day. Picking up and moving things is tedious and slow. Without the ability to zoom to the left and right (like swiping a mouse), it feels like it takes forever to move from the left side of the backpack to the right side of the active stash tab. The stash tab management on the XBox is ingenious, but I would have much rather used those buttons as "Home" and "End" shortcut keys vs. the "useful only once if I buy 100 stash tabs (again)" tab management shortcuts.
Summary:
I've typed a lot and am starting to lose track. I think the XBox version is great and hope that some of these enhancements migrate back to the PC. I know a ton of stuff the past year and a half are thanks to the XBox development and future things (like minion and aura savestate) are still thanks to it, so I've showed my support in double dipping.
I'll be back on the PC, probably around next year because I'm still converting friends to PoE on the XBox
