Looking at MoO there are many more good ideas here then in ES2
I have to say there is also an auto-build function (I didnt remember that) but sicne it starts with producing a clenaup infra on a planet where there is -125 pollution and for a race that does not care about biom as lives on lava world- I would say its not working
I also like that fact that invasion has infantry+tanks and there are planetary shields and porudction can be trasnfered to other planets - all very cool stuff
but:
1. Starlane cripples conflict as the player is always blokced from more complex and interesting diplomatic situations
2. Max player count on the larger map is 8+Player. This and the game has 14!!! factions. This is simply baffling and outside of UI beign designed for 9 factions max I cannot for the life of me why anyone would do this to their own game - its crippling
3. There is also no alliance as far as I could tell and the dimplamcy really just boils down to war
4. Building menu is separate from planet MGMT menu - Both SiS and ES2 have avoided this huge UI design mistake -many many manny clicks
Still: visually this is a much more refined product then ES2
The only thing I would love to see from this game in SiS is the part on infrantry and planetary shields - those are cool though even here it wasnt clear to me how one can use tanks for offense - I dont think it is possible or the game hasnt been developed till the end dont know
