I have to add some things I like about 4e. Just cause I feel I need too.
It’s genius in its approach, the 1st PHB is like a very light simple game upon first interacting with it. While still being the actual rules you’ll use in play. I dint think any edition has done that as well, not even B/X or the red box. It then has an organic way for you to wade in deeper and almost unconsciously become more expert at it.
Balance was fantastic. I still appreciate and miss that even now.
Interaction between players was extraordinary fun. And it did what it set out to do, players downtime during combat was almost nill.
There are more things but I’m going to post this.
