And this is for 2 reasons:

1. The game has Sonic, which all related elements belong to SEGA and the Sonic Team. Could lead to copyright issues.

2. It can trigger some people, and then they might start to make several rants about how “illegal” this is, which I’m not entirely sure, yet.

I do have the feeling that this game is somewhat original because my friends and I made up the plot and created our own Anime character in it, which is Lailah. But despite that, it does have several content form other games like Sailor Moon and Ghost n’ Goblins.

I’ve been so confused with this kind of mixtures in one game, and I have never thought of someone might do something like that. So, I decided to speak to my girlfriend. We both did agree that Heaven Saga is kind of our thing, but again, it still does have content from other games. So, we both decided to make some a bit of research. We couldn’t find of lot of sources that explains the exact issue, but all of us can agree with the fact that it is wrong to steal content and then sell it, which is illegal.

So, my girlfriend and I concluded that we have to remove the TM symbol, just to be safe.

And in case if some of you aren’t aware, yes, I already know a lot about copyright, trademark, and brand stuff. I’ve did myself research years ago.

I would also like to give some advice here for people who like to make fan games.

If you’re making a fan game, be sure to have at least some originality in it. Remaking a game is fine, but you might need to do some research about a certain company’s perspective, regardless.

As an example, Nintendo doesn’t like fan games (which means they can take down and/or sue any kind fan game they want). SEGA and Capcom, on the other hand, they approve and liked fan games (as long as they’re not monetized).

Those of you who make games on Scratch, yes, fan games made in Scratch can lead to copyright issues, no matter which engine or language you use. You can’t make a game and then love it solely, or else you might have to deal with legal issues the hard way.

Not all companies like fan games or approve it. Nintendo for SURE is one of those who hate fan games. So, don’t make any Nintendo-related stuff. It won’t be pretty if they found your game. SEGA and Capcom liked fan games because they like to see how others love their brands and then make something extraordinary out of it.

But either way, it is still highly recommended to do research about a certain company before borrowing content.

Be careful on what you make. And just because you can do something doesn’t mean that should do it.
