I found 2e to be a long series of disappointments. I wanted to like it, and I bought the core books as soon as they came out. That was the first disappointment. I found the writing dry and colorless, compared to 1e. I found the interior art (that blue stuff) to be abysmal. I missed things like demons/devils/assassins, and didn't buy the justifications for their removal. Most of the rules were pretty much the same, but others seemed like changes that didn't add anything, or were unnecessary (an actual change where a clarification might have been better). The DMG stunned me with its slenderness and mediocrity; my reaction was "*this* is the DMG -- where is all the cool stuff?" I thought the concept of the 3-ring binder Monstrous Compenium was good, but poorly executed. I didn't like the most of the art, and putting more than one monster on each page ruined the "build your own binder" idea. And the pages weren't perforated properly and didn't separate cleanly.
Then the adventures and supplements started coming out. I found the splat books and kits to be the worst kind of
bonus/numbers inflation. I thought the adventures were...less than stellar. It didn't help that 2e tended to continue the "storyline" focus that started in late 1e with DragonLance; that's not my style. I've always liked Greyhawk; the 2e-period's treatment of Greyhawk was just pathetic. The premier dungeon of the setting released as a joke module? Gargoyle? Childs Play?
I still bought 2e products, for a while. I kept thinking and hoping that the next one would give me that "*this* is cool, *this* is D&D" feeling, but they never measured up. I kept being disappointed, and eventually I stopped buying. As I mentioned, above, I only ran 2e for a short time before converting to a BECM game, and other systems.
Long after I had quit running 2e, I played in a 2e game that used the "2.5" books (Skills & Powers and the expanded Combat book -- whatever that was called). That confirmed, for me, that 2e had continued down the path the early splat books seemed to suggest, and that it wasn't for me. Rolemaster did that kind of thing a lot better, if I wanted that kind of game.
There were a few 2e products that I liked.
Return to the Tomb of Horrors was good. The historical reference series was good, too. I still use those, sometimes.
