With the bounty ended, and I still haven't gotten the answer, I have awarded the prize to El-Guest. If eventually, I get the answer, I will award the correct person 50 rep as well. Thank you for your answers though.
So, my friend is kind of a video game addict. He knows a lot of obscure video games and I don't think anyone has cracked his riddles yet. He came up with five games that I don't think I've ever heard of. If you think you can crack them, take a shot at it. Please note that, if you do answer one, but not all of them, explicitly state which one you're answering. Also, if you answer all of them, place them chronologically in your answer (don't go and put Number 4 at the top, and Number 1 at the bottom). It'll surprise me if anyone can get all five of them, but here's hoping. Also, he stated as a hint that if you could crack the code in chronological order, the first letter of every video game should spell out
One day, into a mansion, enters a man,
Then a demon used him for her plan.
The brother of the man soon came by,
And he feared his brother may soon die.
A seemingly benign man turned out to be a traitor,
But this is revealed not sooner, but much later.
And the so-called demon who had been sealed away for years
Is finally free, and leaves behind the blood and tears. SOLVED
I am considered the weakest in the trilogy, as I have one less story than the others in the updated versions. However, along with that, I also had the first true bad ending in the series. Of course, every story has a bad ending in this series, but my last story had the first confirmed bad ending. But my successor promised this fact: the bad ending is not the true ending, as proven in the second story in his game. My successor is also the reason why this riddle is not in poetic form, as a character from the third game is a poet. Finally, I must say that while a story is typically chronological, my first story came after the second story. SOLVED
The main character in my story came first in a TV show, as well as the villain,
And yet, not a single character is this tale is human.
You might think at first that Earth is not a series of floating islands connected by bridges, and you’d be right,
But the fifth and final world proves you’re not on Earth, you’re in space, which to you is another plight.
The game itself is hard to find,
But you probably still know these characters because they’re somewhere in your mind. SOLVED
With just two lines, do you think you can solve this mystery?
You’re on the case and you’re chasing her through history! SOLVED
Finally, please note that for this game,
The game has more than one name.
The king who rules over this whole storybook,
He has more than just one look.
His kingdom he rules over with his hand,
From the computers to a pyramid land.
The king has the power of fire, like A Zone.
And yet, he was banished to live alone.
A world in this tale has many sweets,
But the desert still has many treats.
This game has plenty references to others from the same company,
But it is a good game, too bad the people who know it is not many. (Still Unsolved)
Hints: These hints are only for 5, since that is the only one remaining.
While this sequel is not that well-known, the original game was rather successful.
AND (and this is the last hint my friend will give.)
There are many forks in the road ahead, but only one path leads to a good ending.
