I miss it about as much as I miss games with fixed cameras.
In other words BWAHAHAHA WHY THE FUCK WOULD I MISS THAT? Seriously, it was a cheap way to give the illusion of 3D, it was a top-down with a few smoke and mirrors thrown in. It's good for games where you need to see a lot, when individual units are not important, When you're a commander and not really a participant, RTS's for example...but not for anything else.
Modern RTS's (starcraft 2, for exmaple) work well with that kind of view for the above reasons, but RPG's...no. Not anymore.
