Not gonna lie I love this simple, original, gamble-free and click-free version, even if we exclude the nostalgia feeling.
( No Tutorial is fantastic btw .. )
However it should be sped-up a bit.
Prolly by perma -Xp - Speed etc. bonuses so that things don't take forever.
Then we would need some scripts for the obvious lack of conveniency
As for Forts it was flash-player back then and that won't work now so idk if HTML5 is possible.
Btw just saying, the 15 years old patch works much better on phone than the current version.
Well, almost.
Page isn't adapted to the 'modern' window-size/resolution and the map navigation is.. well.. not existent. (though that's not really different from v2.0

)
