Sadly OS don't include NI in the sources I used, and RoI would require hunting down a different data set. Likewise for France and Norway which would be on the edges of the map. Perhaps another goal to add... though prioritising getting the rest of the stuff done for mainland GB.
thanks for the explanation
- about Av9, i believe it s not much different from AV8, i think it gives just a few more parameters, but i m also not so familiar with it...
-WAS, is pretty much giving you a very large choice of "real liveries" for the most common commercial planes existing, especially in modern era ( i believe te graphics are based on Pikka's work(AV8 & 9)
-for the Rvs, i understand the name polroad or hungarian truck might make you think they are specific from those country, and in a way it s true for the early era of road vehicles, but in modern era, they propose Volvo, Renault, DAF....trucks, so those i believe are quite common all around europe (and not specific to poland or hungary)
-i think just TBRS is enough (it includes one kind of PB viaduct)
- TTRS seems to be widely appreciated so it ofc a pretty valid choice, but now given the scale of your scenario, i would not advice you to use this set because it tends to build skycrapper in town of relatively low population, and make the large cities clogged with skycrappers (imho)
--> Tai would be quite nice for the scale you use i think (only if you "differenciated" the "cities" from the "towns", because Tai might severely limit the size of the towns (cities are treated differently)
--> also i understand swedish/polish buildings don t sound at all british like, but i think those sets are really good because they arent filling towns with skycrappers, and again european architecture isn t that far away (beside a few specificity ofc), and this is especially true in modern era.
-And relativ to eyecandy, i was only meaning you should load in the newgrf list, a few newobjects set so players can build eyecandy structure when they want, not that you would place them in the scenario, that would be way too much work and by not prebuilding them it will leave more freedom to players on where to build (without caring of eyecandy that would be pre-existing)
-Also for ECS/FIRS, i understand it require more work, but i have a feeling replacing oil fields, coal mine, iron mine, steel mill, powerplant, farm, forest and sawmill would be quite straight forward (they exists in those both sets)....what would be left are the different kind of "factories", and a few additional primary cargo (sand, rocks,etc)...so maybe those additionnal "industries" could be just placed randomly, while the other you know where they are could probably be easily replaced by their "FIRS or ECS" equivalent.
--> Though i m not asking you to do it ! i only have made suggestion about what industry set you may use
Good luck with the scenario
