Ok, before you read this or reply in this thread you agree to the following statement:
This thread is not a place for me to defend my own decisions for my game or my own systems, I recognize that NAMK is not talking about me directly, is not pointing fingers, and is not directly criticizing anybody, and I will not take this thread as such or react in such a way that it appears I believe as such, if I attempt to do so I give NAMK permission to molest me with his mod powers :V (but seriously, don't do that here).
Copying, modifying, duplicating, fan games, tributes, what have you. I'm getting kinda tired of it.
I can understand borrowing music as that's an extremely difficult resource to create, however, using FF7's battle theme in your 'original' game is not a way to win points with anyone but FF7 fanbois/fangirls. Or using graphical choices like Hearts for a health meter, which was used in every single LoZ game to date.
Using Touhou characters or CGs from other games or visual novels for an 'original game', or nearly copying a storyline or concept, changing a few names and some graphics, and calling it yours.
As you can tell, I'm not a fan of copying at all. Inspiration is one thing, resourcefulness is another, but when I see games using graphics and music and stories and etc... from huge franchises or well-established titles it really bothers me. To quote VG Cats: "But with more people playing games, doesn't that mean we get more games to play? NO. Instead we're getting bastardized versions of what were once classic games. A perpetual easy mode filled with quicktime events and mini-games." I could not agree with this statement any more than I do right now, and seeing the flood of RM games with such a severe lack of originality is disheartening. I want to see the industry give me something new, interesting, a challenge, rather than the same old crap that somehow sells to impressionable franchise-worshippers.
tl;dr - stop copying your favorite games, being inspired and making similar games is one thing, ripping them off is another.
