I quit d&d after 3.X I play something else now if they did make a new MMO I'm sure I wouldn't like it after all they kept making changes to MTG until I decided I had enough
I know this is gonna show my age (im half a century old if that matters), but I quit PnP when 2nd ed went into 3rd ed. After this point it felt like DnD was just getting commercialized and crapitalistic spewing of filth and "redesigns to keep it fresh" were starting to come into the picture and I was like "meh. I will stick with 2nd ed and not go 1 step further!"
And for 35 or so some odd years, I haven't.
Now there's people on twitch PnP sessions and they are like ninja turtles or something...
DnD ain't what it used to be, so in essence saying "There isn't an MMO that's based off of DnD" is a correct statement, just depends on conjecture and how you look at it. For me 1/2 edition (ADnD is my all time fave and it should have stayed that way), is actual original DnD, but everyone's different.
For games thats as close to DnD as possible id say the 2 that jump out at me are Baldur's Gate series and Neverwinter Nights.
Fun fact, I was modding Neverwinter Nights and wanted to implement some custom sounds from DDO into the sound effects of NWN and so I had to download, install, and patch this game just to log in and copy the bard song tune and implement it into NWN and I decided to give this game another college try....
To which I am already beginning to regret. It is what it is I suppose.
Give me Githyankis, Tarrasques, Beholders, Hook Horrors, Wights, Red Dragons, Elves, Dwarves (and pure classes!), Gnomes and Halflings -
or give me death!
DnD now in it's current form feels like its off-base and full of bloat, like much in the west.
