Great Wyrm
It's that way with 5e for me, I started with the basic rules. But I wish they would add more options for hardcore players.Games that work for me these days have reduced mental buy-in. If I have to know all of the crunch straight away - I am less likely to get started. However, if the basics are easily grasped and then added complexity is an option - that I can do.
My sons recently got into battletech - I remembered the old days and numerous rules - but they have a great starter box and we were playing as soon as we had the mechs painted. The regular rules add complexity, but it is in a digestible way. If they would have hit me with the full rules right off I would have passed on playing.
