Nah, that got dragged into it, somehow.
I was wondering why they hadn't updated the related boardgames to readily segway into 5e. Or rather, I was finding the story as to why they didn't odd and even a tad contradictory.
It's not any kind of simple, and need have nothing to do with the relative success the game is currently enjoying.
I answered this pages ago but I think it got lost in the scrum. Well, no, you brushed off my point by saying that 5e looks like 1e.
They haven't updated the board games' mechanics to 5e because, at low level, the 4e and 5e mechanics are virtually identical. There's really very, very little difference. Particularly coming from a board game where you don't have the chargen options that you would in 4e. So, you have your low level character with a handful of powers and off you go.
Mechanically, at these levels? 4e and 5e are so close they might as well be the same game. So, why bother changing the board games' mechanics? They work just as well as an on ramp to 5e as they did for 4e.
