Well, if Morrowind and Daggerfell are like Oblivion but are supposedly ten times better then hells to the yeah, I'm gonna check them out too! Much the better for me to be an Elder Scrolls fan if I play all of them!
I personally feel Oblivion is a really really really great game from the days I've just spent playing it non-stop and I've sampled a few adventures and RPGs in my time. It's like a personal, fantasy style Second-Life, but without the crashes. Plus it's really beautiful and in your face instead of cheesy like most non-Japan RPGs. But yeah, I'm not trying to start anything, besides you said it was good, just not as good, so we're cool. If I get the money ever I would love to check out the earlier Elder Scrolls and see for myself.
Whoever designed these games is amazing....I never thought I'd see the day when the beauty and driving story of a JRPG met the customization and free will of american (?) style roleplaying.
