I have to be the voice of dissent. I played it for a few hundred hours (but
nothing like the hours I sunk into Diablo I & II!), and for the first few days of play it was almost more fun finding bugs and little "polish issues" than the actual game itself.
PoE is the diametric opposite of the quality you see in a typical Blizzard game.
It's fun in its own way, and it is free, but calling the the "best RPG available" is a stretch.
I had a list of all of the issues I found, but I lost the text file to a PC upgrade, so I won't type them all out here, but the most glaring one for me was that when you moved from one area to the next, the door orientation was inconsistent/random, so you'd often end up going click-click-click to move and then move back to the previous area by accident. With the slow loading times this was particularly frustrating.
I've had debates with PoE fans, and they gaslight me by telling me that "there are no issue", "the game is perfect", etc...
That's actually an interesting psychological phenomenon all by itself! People can get acclimatized to anything and learn through trial and error what to do to avoid issues. For example, I learned to avoid the door orientation thing by pausing the move clicks when entering new areas, so I stopped noticing the bug. But the bug is still there! It didn't go away. I changed, the game didn't.
This is why players with 1K+ hours in PoE swear that it is awesome, polished, and bug-free. They don't even realise all the tiny habits they've picked up to avoid the bugs. It's like knowing to double-click desktop icons, but single-click web URLs. This isn't consistent. It isn't good. But people learn and get used to it, and stop thinking about it as a problem... until they watch Grandma use a PC. That's when you realise... oh... it's actually a terrible, unintuitive user interface.
This is why Microsoft famously used to use random people off the street for UX testing. Internal testers learn to avoid the rough edges after years and years of clicking around the same GUI.
PS: I just remembered another glaring bug. Setting the game resolution to 4K would set the monitor resolution to 4K, but the game would render in 1080p and upscale. This wasn't a feature, the game simply couldn't write the value 3840 to the config file because there was a "sanity check" in the config GUI (why!?). If you manually edited the config file, you could play it at actual 4K. Again, people would swear up and down that no-no-no, I was wrong, it's a flawless game and runs buttery smooth at 4K, etc... meanwhile they're playing a blurry game that they just assume is "the PoE look" and some sort of stylistic choice.
