/vt/ - Virtual Youtubers

So while Ive been deving this little pvp rts mini game Ive been taking a ton of "inspiration" from FFXIV.
Does feel a little weird sometimes though, because whenever Im coming up with systems or in this latest case, UI, Im just straight up copying design choices. And I feel a little bad? but I keep telling myself theres no need to reinvent the wheel (theres only so many ways you can show a cooldown or a button, right?)

This certainly has to come up with regular writing or story telling though. you read some story or watch some show or movie and think "wow, thatd be cool to have in my chuuba nation"
How do you all reconcile with the feeling that youre "stealing" an idea? Or am I overthinking it way too much and no one else really cares about this?
