Slitherine

How is this different from Gladius - Relics of War and Sanctus Reach?

If it is just like an expansion, just in a different setting or different era, then 'm not sure that I want it. But if it is a completely new game with different, improved, or more interesting/innovative game mechanics then I surely want it?

they are games completely different. gladius relics of war is a strategy turn based, you build a civilization and with resources build army
sactus reach is tactical game, you have point list to choose units of your army and to fight against enemy army with same list points
in sanctus reach setting is more realist like other turn tactical turn based games
however the problem with sanctus reach is it has little factions, and others limitations. it is unfinished game. slitherine left game
gladius relics of war is a finished game
