You could make a .BIK video and play it with http://www.creationkit.com/PlayBink_-_Game. The intro sequence is all game, the player being the cart I believe.
Edit: Appears the text is not a BINK.
Yeah, it's not a bink. I've done binks in previous games, but it wont really work here. In previous games I've had a fancy cutscene, the players controls are locked out, and things happen. At some point during all that stuff, I sneak in a bink video with some quick text on it. However, here, the player opens a gate, thus opening their view up to see my entire land looming out ahead of them. It would be a wonderous moment for some titles to fade in, like my name or the name of the mod. A bink would constrict this feel severely, as well as being either poor quality, or immense in size.
The entire cart intro is ingame, and the titles are done somehow. I just need to know if it's something I can utilize with my own titles, or if it's hardcoded or something silly like that.
