The screenies are from Absolute Annihilation (my personal favorite mod). The units next to the Krogoth would be the KrogTaar heavy weapons mech and the Shiva amphibious mech.
I like the idea of the map, and where you are going with it, but I think it still needs a bit of work.
The highway would look cooler, I think, if it looked a bit battered and used, as opposed to pristine. It would feel more like you are fighting over a real battlefield, as opposed to an artificial world. The bitumen should look worn, you could put cracks in the tarmac, even some craters and rubble. If you are able to use features, I suggest putting some burnt out unit corpses on the road. The highway could perhaps be better if it was much wider, so you could fit more units on them.
I also think you should provide trees in the space on either side of the road; quite dense trees infact. Perhaps some terrain undulation (hills, etc) too. I say this because I think that that particular area is a little dull, and needs some livening up, but also because it could effectively force many vehicles to stick to the roads, and make kbots an excellent choice for taking the off-road path. It would mean that players travelling down the road could fall victim to an ambush set in the trees, etc.
Not to shabby deci... I think the thing I'd like to see most is a little more beliveable coloring in the grass, so it's less "neon seaweed"... maby a foresty color...
Yeah, a less tiled map would probably look better, the grass could be a bit paler and more dead looking, the road could use a touch of cracked concrete (not too cracked, just slightly).
A very cool concept - but it just plain isn't finished.
Things it needs: shoulders/medians to make the road look less like 2 simple lanes. Gravel shoulders would be a good way to make the hardness peter in gradually rather than having an abrupt jump between soft soil and hard asphalt. Nice ditches on either side would be good too.
Also, some more features around the side of the road - just like little turning areas, communter parking lots, stuff like that. I know that adding buildings would be too much modelling, and adding other roads would break the flow of the map, but you could add some features.
That, and street lamp features would be cool.
As for the landscape itself - it looks rather unnatural. I'd keep with the pseudo-terrestrial theme and try and make it look like rolling farmlands - texture it with alternating crop rows and suchlike.
I have updated Road to War to version 2. It now has visible metal patches, better metal distribution(less in the center), and kbots are now slower on the highway(to make commander defense of the center less effective, lowered to 1.5 multiplier from 3.0)
This should fix most of the non-graphical issues with the map. Next version should have a better texture, assuming I can remember how I did this one in the first place.
