I dont care if it is 3D.What matters is
1.to be well structured
2.to have good gameplay
3.to keep it simple (or with option to be played in a more complex or simple way)
4.to avoid so heavy 3D fx that we will need to upgrade again !
If done properly , it will not NEED the 3D to be a good game.But it WILL be there so we might as well enjoy the fx too.
Lets hope Sid Meier doesnt flop this....
