No worries. I remember disliking the combat in U7 as well, but the story was so awesome that I just didn't care! I also disliked that basically the Avatar was the only one that could do magic at all.
When I say that U6 started more to attempt to be more 'real,' I mean the graphics, not the combat. I don't seem to have a problem playing the first five and imagining what it really looks like, but with the later ones, the portraits, the sprites, etc. just look so rudimentary that I have a hard time making the same jump, though they were breath taking at the time.
I guess what it comes down to is that when I think back to the first 5, I remember the blocky characters and 4 colored world, so I get what I expect. When I think back to anything with a sense of realism, I remember it looking so much better than it did, so I end up disappointed at first! Damn tricky memory!
I liked U6 to an extent. Good premise, huge step towards what we think of today as modern games yet enough of the old school to keep me happy. One problem I had was that my brother and I quickly figured out how to about 50% through the game due to a plot problem. The thing was, we didn't realize we'd done it until it was too late! I did later go back an play it through without cheating but it wasn't the same thing as experiencing a truly epic event the first time.
That said, I enjoyed the two offshoots using the same engine much more!
