Recently I saw available in a store both Stronghold Deluxe and a Pack containing Stronghold Crusader, Stronghold 2 and Stronghold Legends.
Both offers bear good prices. Stronghold is much cheaper here though. I noticed that S2 is not the Deluxe version and that the S1 version here is not Deluxe.
What I want to know is: What is the better option for me? I mean, if I buy a non Deluxe version, is it upgradable with the same content as the Deluxe copy?
I know that the Crusader Extreme version adds a hell of a lot of stuff that is not freely available to owners of previous version.

I have heard that Stronghold 2 and Legends are not nearly as good as the 2D iterations of the IP from most people(Youtube comments) and really 2D games are best for me anyways until I am old enough to get myself a better computer (I'm almost fifteen).
