I actually think that the DCS-series is starting to look quite good, I would however love to see some more variety in the scenery. Every singe town and city in DCS looks the same, as do the ground textures, but still, its getting there, Warthog is a huge improvement over BS.
And as said before, I know that the ED team has a lot on their hands, and that there simply isnt enough time to add everything that we would like to see, this could easily be added by the community, if they just released the tools.
