the WotC got it and it has flurished and gone no where but up (buisness wise) since then
This is just factually wrong lol. Like just incorrect.
D&D made a lot of money at first in 3.XE, but then tapered off, and Hasbro became unhappy with it. They actually threatened to vault it or something similar, if it couldn't make more money. Hence 4E, which was an attempt to reach Hasbro's $50m per year goal. 4E initially did okay, but never came near to meeting expectations, especially with a divided audience, and profits, and Hasbro's interest in it has declined steeply by 2012/2013, at which point Hasbro, considering D&D a lost cause, and not, at the time, having any particular financial goals for it beyond "Don't lose us money", let 5E be made. 5E wasn't, AFAIK, absolutely huge out of the gate, but grew fairly rapidly, especially after about 2017, it was growing fast when the pandemic hit, which caused to grow even faster. Now we're actually in a slightly strangely 4E-like situation - Hasbro is pretty happy with D&D, but thinks it can do better, I forget exactly what the goal number is now, but it was hundreds of millions. Hence 1D&D and the 3D VTT, which is investing vastly amounts of money in (far more than it spends on D&D, if the employee numbers are right).#
So it's not true to say D&D has "gone no where but up (buisness wise)" - D&D has been a bit of a rollercoaster. 5E has gone pretty much nowhere but up, so far, but we'll see if that continues indefinitely.
