Considering I bought TES-Skyrim as part of a Sale Pack from STEAM (including: Hunted-The Demon's Forge , Brink, Fallout New Vegas..etc. for $49.00 and got the Dawnguard DLC for $20.00 bucks, I felt cheated when the DLC was causing CTD's all the time, and random lag/FPS spikes/drops!
2ndly, when I first began playing the game, (B4 getting DawnGuard), the dragons came at you fast and furious, ( by lvl 18 I had 27 dragon kills, of which only maye 9 were hunted down via quest-line, or random 'roost finds'), ..after DawnGuard, I can't get enough souls to fill out my Shout list!!!
Finally, the whole "Vampire" thing has been DONE-TO-DEATH!!!!! There are no "thoughtfull, emotional, helpful Vampires" out there!! Vampires are Feral creatures, they EAT PEOPLE TO SURVIVE, PERIOD!! Please dig into your 'ideas hat' and pull out something new!!
All that said, I am still enjoying the game, mostly, and really having fun with the Creation Kit!!
I have personally designed 3 player homes for myself, (too self-conscious to upload them), which makes me happy you are giving that oportunity to all players via Hearthfire. =D
Thanks for your attention, Squashy
