I originally bought an Xbox purely for the release of Oblivion. There weren't any platform exclusives I had a bead on and so the choice was based on my love of TES games. I was lucky. I never suffered the RROD and even when I gave the system to my ex's kids it still worked fine. Later I bought a PS3. I loved it more than the Xbox for several reasons: the controller was more comfortable (and no battery pack), free internet, Blu-Ray, it didn't sound like a rocket engine while running a game, etc... Oblivion GOTY came out for it and again, I was blessed (this will be a trend, trust me) and the game ran fine without issues. I got FONV:UE. Ran fine. Skyrim. Ran fine. Every other game. Ran fine. Blessed, I say.
Now I am hesitant to say that DG would most likely run fine on my system, but the dev's are iffy about it on a whole. That's fine. I'd hate for it to come out and ruin my perfectly running Skyrim. However, my only fear would be to lose DG and get HF instead. I've said it before, and I'll say it again: the premise to me is about as enticing as mounted combat. Mounted combat, to me, was (and is) useless. Even on my warrior I gave up on mounts when I began playing the game months ago. I even killed Shadowmere because on a fast-travel-spawn it pushed me off a ledge and killed me (more than once). I don't do mounts. I have fast travel (and there was one person who asked "how did you find cities then?" I responded "coaches. They are available in all major cities and are dirt cheap"). Building a house has a kind of "aww. That's nice" feel. And don't get me started on adopting orphans...
In a nut shell I stay on the fence. I do agree that if problems were foreseen (as it seems) when developing/porting it, then keep it to the system of choice. I patiently wait for DG to come out and slightly grumble at the release of HF, but I understand. Hopefully the issues will be resolved soon.
