Hello, I own the original game from 2008 and have not played it since about 2011. I have two primary questions.
Is there a way to move the game into the Steam platform or will I always launch it and play it on its own?
Is there any advantage to owning the original? I guess what I am asking is if the original is required to play the Rebellion expansion, or is that considered its own game? Is rebellion the most updated version of the game or is there a newer version? I see there are many expansions, but not really sure where those all fit in.
In summary, I really loved the original and thought I would like to play again, but was not sure where I should start. I was able to recover my software key and download the original game, but I did not want to do the actual install until I got some guidance. Thanks!
The original Sins has never been on Steam. Stardock allows those who registered the game to continue to download it from the Stardock store website.
Other than nostalgia, there's not much point in playing the original Sins. Rebellion has been out almost 8 years now, and it includes all the features from the original game, plus the Entrenchment and Diplomacy expansions, plus more original content like titans, subfactions, and victory conditions.
In addition, at this point the mods for Rebellion far and away eclipse the ones for older versions in quality.
In short, Rebellion is the version everyone is playing and most of the player base is at. Rebellion is a "stand alone" expansion, so you don't actually need any of the previous versions to play. At one point they were offering $10 discount on Rebellion if you already had Sins, but I think that expired, and you can get better deals on a steam sale anyways.
