Re: [Discussion] Crestwood Please explain
It was "story reasons" as having a dam fill a fairly large area takes years most times, but for the story that wouldn't work. Just like opening the dam also drains it in a day.....which would flood a huge area down stream, so that doesn't make real world logical sense, but is again for story reasons.
As far as towns being upstream and flooded by newly built dams, that actually happens in the real world, and yes they notify, buy out and move people well before the dam is built or lake filled, but having structures, roads, and leftovers underwater isn't uncommon at all, I know of several lakes around my area that have old roads and you can find old buildings underwater if you know where to look.
So, basically just story hand-wave and it is a video game, and NOT 100% real or logical.....honestly, there are worse errors in this game if you go look, but to each his or her own as to what really annoys them on things like this......
