1. Do you avoid Forgotten Realms products?
2. Do you like either Pre or Post spellplague only, and if so which one and why?
3. What Don't you like about Forgotten Realms?
All of this is personal opinion etc etc disclaimers blah.
1. Almost but not quite entirely; I got the original grey box, the Ruins of Undermountain box, some 2e monster books, the 3e Monsters of Faerun book (many of the monsters within which were not really FR monsters at all), and... hm... I think that's about it.
2. No, although I prefer the "original era" FR over everything that has come since. By which I mean, FR with NO extra supplements past the Grey Box. Other than that, I like FR 4e, as it has done away with much of the stuff that I didn't like about it.
3A. Elminster, to start with- which is one of the things that 4e did to the Realms that I love: get rid of 90% of the "superheroes". There shouldn't be enough ultra-powered high-level good npcs in the campaign world that you can't explain why the bad guys haven't had their asses kicked long ago. But this is the least pressing bit of my dislike for FR. Add to that...
3B. Stupid mechanics, mostly in the 2e era, but bad enough that they forever tainted the flavor of FR for me; or the bastardization of things that were much cooler in their previous incarnation in my opinion. Bladesinger, I'm looking at you as one type of example of this. Spellfire, you're another. Drow as pcs- although originally in Unearthed Arcana- I blame your popularity on FR, and I still will never allow you in my campaign.
Drow are better as monsters than they are as player options.
3C. By far my strongest hate, and again, large eliminated in the current incarnation of the Realms, is reserved for metaplot. Although this applies quite as much to other campaign settings (Dark Sun 2e with your goddamn IMMEDIATE REVISION OF THE BOXED SET RIGHT AFTER IT CAME OUT), FR seems to be a pretty bad offender. I don't want to read crappy game fiction to know what's happening in the campaign, but if all the supplements change stuff around in response the events in novels, rather than reading crap novels I'll stop buying crap-required game products.
