I believe WC3 maps have a similar option:

Map always visible (Can always see everything, like in OP2)
Map partially visible (Fog of war, map terrain starts completely revealed)
Map not visible (Fog of war, map terrain hidden)

No we cant do that because every one has to make it like every other RTS out there and have the unrealistic you cant see any thing till you move 3 feet that way and expand the field.  

I dont deny that it would add a bit of hardness to it because you wouldnt beable to see just how many tigers are coming.  But remember would you want to have a fog of war when you have units like the star flares and novas that some people are just great at sneaking around.

The only thing i see that validates the fog of war at all is the lag.  But from what I heard youll only beable to see a set distance so your computer doesnt lag down because your processing the colony that is on the other end of the map and would just process what ever is in your view region.  But it would be farther then a fog of war would let you see so if some thing was approaching you could tell.

I agree.

QuotePeople ever heard of Day/Night?   And ever heard of turning off lights?   It works wonders.
I'm hoping you OP3 makers will stick to that lovely little feature

Yes, day/night will stay. Its not the same as FoW though.

Thats good. I like day and night.
