I only played the remake of FFIII on the DS and wasn't a fan but also didn't get real far in it.
FFIV on the other hand, I've played just about every version of it. Back when it was new, it was pretty awesome but it just doesn't hold up today. The story parts that made it great then because other games didn't touch that stuff was cool but not a big deal in games anymore. The gameplay isn't super broken but really isn't anything special. The sprites actually moving around in scripted sequences was ground breaking then but meh today.
Still though, even though it doesn't quite hold up it's still a good game. 7.5/10
