Information overload is also an extremely limiting factor. One of my favorite things about EQ was not even in the game but because of the time period it existed. No in game maps so players would draw out maps of the zones and put them out on the internet. EQmaps was the source to understand these things. Recipes and quests weren't datamined like they are today as datamining was in its infancy in comparison.
You had to go around and ask other players how shit worked. Discuss in forums or in game. Especially early vanilla spell research. You and other scholars of the arcane had to figure out how to craft those spells and hunt down the information yourselves. The world was dangerous and terrifying.
That won't happen anymore. MMOhead will datamine everything months before release and you'll just easily search for whatever you want. Kills the wonder and what you can discover unless you intentionally limit your interaction with the rest of the web which just isn't that realistic anymore. A game that captured the magic of early EQ and to an extent wow classic just isn't possible now.
To this day I absolutely love shit like this:
