The Settlers, a great game, expecially the III and IV (that i'm still playing sometimes). This is a perfect example of well made economy where everything is linked together, from trades to buildings, from gathering to combat. Also a great example of functional territory control and regional resources.
If will be good is some features of it are added to LIF, imagine a kindom that to be autosufficient need different kind od specializations and professions into the owner guild, trades to other kingdoms, and build a military force to defend assets, expansions, resources, and so on.
A very immersive and a true sandbox experience where everything has a meaning and everyone has an active role.
Lots of sandbox nowadays, DF and MO for example, forget the sandbox and socialize part and waste all the resources mainly for the massive combat, clan warfare and pvp while everything else is less developed and relevant.
These games aren't sandbox at all but hybrid brawlers disguised as one. DF is the perfect example of true potential wasted, 10 years of ideas and development trashed, expecially with the horrible 2.0 incarnation, completely different from the original vision of Razorwax back to 2001. T_T
ps: Sued for what? Then every RTS should be sued because is based on the same principle.
