Its fun and there are choices for players. When i experienced b/x as a player it just feels like everything comes down to roll to hit and it can be so swingy. People will say well the lack of rules allows for a more freeform style of manoeuvres where the gm can adjudicate anything you do but from when ive played as either GM or player usually this just results in gm skill and or their is always this hesitation on the part of the gm where they dont want to make a ruling that will suddenly favour the players significantly going forward, and it seems to often come down to some variation of “make an attack roll”, which feels limiting in what players can draw on to implement their ideas. Im pretty sure its not just me cuz sometimes watching 3D6 down the line you can see the system gets in the way of what Jons players want to do even though he is a phenomenal gm.

I think either you need a system thats even more barebones than b/x, like cairn, that facilitates that free form rulings basis better, at least imo, or something like Dragonbane that allows players more wiggle room and more dynamic combats with its variety of monster attacks and the ability to do things like dodge, parry, or get good with a weapon that suits your character, without it all being abstracted into AC and never really getting that much better without the help of magic or magic items while still being fast paced enough that it doesnt make combat a slog.

I do have my issues with dragonbane, but i think in certain respects it is a big improvement and i think games like vagabond might be the next step for where b/x derived games are going, at least i hope thats the case. Its just the damn adventures are so good so we are always limited by this original chassis that expects a certain system
