Well personally i think that if u gonna make a fan game of A link to the past for example, u don't make a Bet then up or a Side scroller shooter...
And also i think that if u liked a link to the past enough you may had possibility something new to add to the story as well, so i don't see way would you make a FPS of A link to the past... But ok. At least it worked for you as practice i think... Good luck with your future projects. 😄
