The cutscene is not about the ship. The colossus is merely a symbolic placeholder of everything that is happening in the GTVA systems post-Sol, the terran-vasudan symbiosis, the economic boom, the optimism after destroying the Lucifer, and the acknowledgement that we have undoubtedly surpassed the shivans in technology and scale. That cutscene is filled with hubris, but this is something that is only transpired when you realize the actual shivan fleet scale.
FS2 without that cutscene is simply meaningless.
And then it was simply very well produced for that time, with every single (unimportant) detail, fooling you to believe this was a cutscene produced for a 24rd century pilot, not for a 20th century gamer.
About the FS1 intro cutscene, it is quite a good one. I never got why the Lucifer was just two nodes from Sol, basically at your doorstep, and then spent all the game's entirety trolling the node map, until finally managing to get Vasuda Prime, and just at the end of the game managed to find Sol.
