Well I think that FFVII had a pretty weak battle system as Rei stated. Maybe average, but still not interesting. And I have put up with that game for 2 1/4 turns around. I tried playing Grandia on two different occasions and I was sick to stomach. The battle system was good but....the rest stunk. Xenosaga has a nice blend of battle system and story line. The battle system makes it interesting at times and the story is solid. Though it does not go overboard at times. I have heard that .Hack has a really good battle system once you get used to it and the story is real good.
I prefer to read books any way so call me crazy. But I look for an interactive reading experience in an RPG. No not one of those books where you skip pages just to reach your ultimate demise but, I guess, like a movie with you controlling it.
Games like Morrowind are addictive, for no reason. Morrowind was just....? The battling was just wacky and the story line was ok. I guess being able to join guilds and undermine a guild is good
