Again the same huge complication of being able to build anywhere, the locations will be preset
Yeah i agree, i do think there will be more than one plot per designated hold though. Three possible plots available in that vast expanse seems a little underwhelming. However, once i start to build my first home i won't really care, well, not until i start building my second. At £3.40 for the DLC, i really can't complain, it does sound awesome. Having to collect and craft items in order to build your home sounds great. They could add a perk tree for this alone.
I will probably start a new character build for this DLC, it would be interesting to see the evolution of your home paralel to the evolution of your character. I hope it is available from when you leave helgen.
