I agree, the chants and glow colors of spells are pretty neat in the old BG games. When you're familiar enough with the games, you can counter/avoid hostile spells by relying on the chants and the glow colors. There were a couple times I used Dimension Door to teleport out of a Wail of the Banshee because I knew it was coming (Sion fight, Guarded Compound). Felt pretty good.
That said, Artagel is right in that, this won't matter much unless the game is RTWP. Chants and VFX for spells will still be nice, but they won't have any gameplay value in TB.
