Nice find GOT4N! The first half is definitely new.
There are a lot of quotes that sound like typical RPG quotes, spoken by the supporting cast right before the final battle. There seem to be a lot of characters though, more than in the final version. Plus, every character definitely seems to have his/her distinctive way of speaking. I like that a lot!
Let's guess who everyone is, shall we?
- "Go for it, Rayman! You can do it!"
This sounds a lot like Ly.
- "Take him out and we'll finally be free!"
Murfy, maybe?
- "We're all with you, little buddy!"
Definitely Clark. He calls you "little buddy" all the time.
- "Win, and I'll melt my gold to make a statue of you!"
That's a scrapped character... or maybe Jano?
- "I've taught you well. Don't let me down!"
Murfy, or a scrapped character. If I wrote this, it would be spoken by a very respectable "master" who teaches Rayman all of his moves. It's Ly who teaches Rayman his moves in the final version though, and I don't think she'd talk to Rayman like this. Murfy is possible, as he is Rayman's "instructor" during the game. I'm not sure about this being him, though. Somehow, I can barely picture him saying this.
- "You are the greatest hero I have ever known!"
This could very well be the Globox girl who likes Rayman so much in Rayman Revolution!
- "We'll be dancing to bring you luck!"
Another Globox kid, probably, or maybe Uglette. It could be Globox himself, too, but I'm assuming he was already meant to be kidnapped before the final battle.
I'd like to point out that the "Did you remember to say goodbye to Ly?" could also be spoken by Razorbeard right after Rayman's final conversation with Ly, and right before the battle. That way, it might not imply any strong feelings between Rayman and Ly, although I would be very happy if it did!
I'm also wondering, is the "piranha farm", and the "witch Ly, presently languishing in the pirate stronghold, will be made to walk the plank at dusk" text present in the game? I remember the rest from various in-game signs, but I don't seem to remember those two. I'm guessing they're from an earlier stage in development, where the Robo-Pirates were, you know, more pirate-y.
