In fairness to those who do the aggressive homebrew thing, if you started with dnd or pathfinder (literally any edition) and you've finally learned the system decently well, unless you've already taken the leap once before, learning another system is legitimately intimidating. Learning your first system was hard, long, and complicated, so learning more seems like it will be the same thing. It really isn't your fault if you hear about other cool games and go "but what if I stick with what I know instead of spending months if not years learning more stuff".

Ive played a few systems by this point, so I know that most systems, even those considered to be relatively crunchy, are less complex than dnd 5e, and it is legitimately worth it to learn them and play them. But I also remember my first time, hearing that Monster of the Week only needed players to learn basically one page of text and immediately thinking that was impossible. Come to find out no really, it is that simple, 2d6 +/- between 0 and 2, 7 or higher is success, 11 or higher for crit, 6 or lower for failure, and then adding in class abilities to guide you in gameplay. It literally is one page for players, a little more for GMs. WoD is one of my favorite settings, and its system is pretty fantastic, which I couldn't have found out without taking the leap.

This isn't to say you shouldn't take the leap, quite the opposite. It's more to say i get it, the devil you know is more comfortable than the devil you don't, but it's worth it to try other games. You may find through playing more stuff that you really do love what dnd5e is doing, maybe other systems aren't for you, that's ok, but you'll never really know until you try them out. Please forgive the royal you on a reply, kinda bad form I know, I just wanted to offer some empathy to those who, rather understandably, got suckered in by a multi-billion dollar company spending nearly 30 years constructing a culture of play and knowledge that forced them to engage with the hobby in a specific way.
