in general, i agree. it's just a game and more often than not the system encourages you to tweak it to fit your group. however, i feel like there are times when people fight against the system by trying to hack it apart and rebuild it in their image. while i don't directly discourage this, sometimes this is done at a detriment and without consideration for balance or fun. if you like the changes you've made to your favorite system, and it works well at the table, then keep doing that. but if you're looking for ways to trim the fat, or like the ideas but not the mechanics, then there are so many more options to choose from than monolithic popular game.

i think it's okay to point out to people that there are systems that already exist that solves their specific problems. that's more than likely why they exist in the first place. and this goes especially for those who are new to ttrpgs in general, as there are lots of fantastic options for introducing people to the scene. i readily encourage people to try new things and experience how different systems make changes to the formula to fit their purpose.

speaking purely as a gm, and this is my personal preference, i don't want to fight a system to make it do what i want. if it doesn't, and that's a detriment to my personal playstyle, then it's likely not the system for me. i'm not married to any one set of rules, nor do i want more work to make any one system solve all my problems. if someone else wants to do that, finds enjoyment in that, and does it well, then more power to them.
