Question is, will I still be able to enjoy Oblivion after having played these more recent games? Will the old graphics and clunky animations put me off or will I still be able to sink many hundred hours into it like I have skyrim?
I'm just worried I won't be able to really get into it now that I've been 'spoiled' by Skyrim's graphics....

I have no problem going back and playing games from the late 80s - early 90s, let alone games from the mid 2000s.
I think you'll really like it.
