No. Not ever under any circumstances. Civ IV goes way too far in this direction already. Enough techs and enough effort and every tile should be improvable to be of serious use.
Again, I disagree fervently. Every square should end up roaded and railed, unless the size squares are meant to represent becomes a great deal smaller.
I didnt' write my post clearly, I guess. I want all tiles to be able to be improvable in some way

I don't know that I agree that they should all be roaded and railed - if there is one thing I didnt' like about Civ III, visually, it was that every tile got a railroad.
For instance, a forest preserve should almost certainly NOT have a railroad and most of them shouldn't have roads. Maybe other improvements should have roads, I dunno. All I do know is that in the modern age, there's less for workers to do and there really isn't any way to improve water tiles and that's a real shame.
