But Farrix, the use and need of taking a castle is another story. That belongs into the content area, goods to craft certain bonuses ect.
But when they become valuable, you want to see them defended not just by a default layout.
@ Tomas
Maybe a combination of both and even mix could be a good solution.
-Upgradeable layout where each layout already has improvements where barricades and such are destroyable (pretty sure that a serverside script can spawn props before round begins) via website
-user interaction where the owner can preset props before any battle as a quick change via website 1 option out of 3 or something like that, for example siegeshield walls on keepwalls, double gate, ladderdefenses (spikes) on outer side of roofs.
those props can be destroyed or are not reusable so you would have to buy them before each battle, just like your proposol but premade. (buyable on website different prices only 1 to chose)
-additional props for players to use, not with uberamounts of hitpoints but destroyable in time NOT stackable and the props have to use more space then they take in the real space in game so you cant line them up to make walls and walls
Like ----------- but - - - - - - that way if the props aren't destroyed it still slows the enemies rush by 50%
Sieges I've watched and been to were long enough to build stuff without preparation and people became quite skillfull with it. I doubt that 15 minutes preparation is very kind to the players. YOu have to imagine that attackers would have to wait the whole time. Even though they are the aggressors its lost time. For not building defenders too.
Extending preparation from 2 to 5 minutes should be sufficient.
Tell me what you think
