Thank you for the info, Trippy. I was wondering if I'd be able to keep the characters (when I first played ED we were told we'd be able to bring over the same character to FoV), but was suspecting it wasn't going to happen when I saw the different extensions. What a bummer.
I did re-buy the full Dragon Knight Saga (remastered ED and FoV) because I knew that it'd be worth the little bit extra to have both together. I could technically start from the beginning (again), and play all the way through w/ the updated version, but what a bummer! I was quite rather attached to one of the characters. The disc still plays the older characters.
Oh well. FoV does look great, and so far has seemed smooth with the handling. I have no doubts about it being better than the original release! Love Larian studios!

Thanks again, Trippy. The link you included was helpful.
I recommend other readers who may be wondering about the DVD version of Ego Draconis (ED) and the Dragon Knight Saga (DKS) to visit the thread Trippy posted.
To note: I bought the DVD version of ED. The file extensions are different than the file extensions on DKS-- they are, apparently, separate and completely different versions which are incompatible. Based on many readings of many threads, I would not recommend the Steam version, as it seems many people have had problems with it. Sure, you'll pay more through other avenues (including the whopping amount through Larian store), but you'll likely have better support. I bought DKS through the Larian Store, even though it cost more, because 1) It's direct from Larian, so they should get more of the money; 2) it's direct from Larian, so updates and patches should be immediately available; 3) I am not familiar with digitally downloaded games (other than Divine Divinity through Good Ol' Games--GOG.com; that ended up having game crashing problems, whereas the disc version I bought didn't)...
...hey, Larian has made a ton of money off me! I've bought Divine Divinity DVD twice (a copy for hubby, a copy for me), the digital Divine Divinity (before I found the 2nd DVD), the Beyond Divinity DVD, the EG DVD, and now the DKS!! Escaped pigs! That's a lot. Well worth it though! And my kids can't wait to play Divine Divinity. Maybe I'll let my son buy himself a CD copy (it's down to about $10 in the US).

I'm a stickler when it comes to following rules, and since each of my family members has a computer. . .
Going completely off topic now. Okay, so thank you, Trippy. To everyone else: take heed!
All best,
