Not vidya but
I dislike Forgotten Realms. I mean, I dig the spin off settings (mainly Al-Qadim), and the early 2e stuff is okay. But as a setting? I'm not a fan- might be that I dislike the 'kitchen sink' approach of it, and how the whole 'NOVELS ARE CANON' shit makes it so everything about it is over-explored, and your PCs are going to be in the shadows of figures like Drizz't and Eliminster. It's sort of like why Dragonlance isn't really fun to play anymore- the entire setting has been explored and delved on by the novels.
Also Ebberon is my favorite setting, after Ravenloft because Ravenloft is the shit.
Borderlands is only really fun if you play it with a gaggle of friends, and even then there are better games to play.
Honestly, the problem with FR isn't even that there's nothing to explore, it's that the general setup has left the game series with zero stakes at high levels in the wrong ones. This is less a problem with the setting itself and more a problem of the supplemental materials and certain writers.
Some of the Vidya and TT games of FR though work fantastically well. The problem, in my experience, is when you incorporate the variety of ridiculously overpowered NPCs in the setting into the framework. Elmunchkin is by far the worst offender here, and though Drizz't has a bad rap because of copycat concepts, he's nowhere near as bad as Elminster. It's very telling that the best FR works fucking forget that the likes of Elminster exists and gives the PCs more free reign. Some of the other high-level chars in the setting, like Lord Nasher, can even be kind of hilariously useful to the setting because even though he's a badass who gets shit done, he's pretty much leashed by his need to manage a fucking country, which is, to put it simply, a big fucking deal and explains why he needs the PCs so much.
A big problem is that EVERYTHING NOVEL IS CANON means you have to simultaneously incorporate the best and worst. That means placing your CS Gotos alongside your Dan Abnetts. There's a reason other works declare all offsides work noncanon, and it's to avoid this exact problem.
The biggest (and saddest) bit of madness in this though is how WotC tried to fix this. Essentially, 4E comes out, kills absolutely everyone or ruins their shit in some other fashion, breaks how the entire world works so it fits with 4th Edition, and expects this to somehow fix the problem, and then is legitimately surprised when
fucking everyone hates it. The lorefags are pissed because the canon got shredded for expedience, the center-line guys are pissed because they threw the baby out with the bathwater, and the casual fans come to a setting that is quite literally
unrecognizable. They could have thrown FR out entirely, created a new setting from scratch, and it'd have done less damage to Forgotten Realms than 4th Edition did.
I'm aware that WotC has a history of fucking up settings that would have
sold themselves (not producing Ravenloft or Dark Sun through the entire 3.x era, just as an example), but that's still an amazing mismanagement.
