I'm sorry if my title doesn't make much sense, I just couldn't find the right word for "Having monsters actually visible and will chase you when your spotted and when you are touched then prepare for battle, but maybe they notice or chase you a bit differently depending on the monster type" The last idea is pretty much like Xenoblade, mostly because some monsters will react to the characters in different ways, maybe they react to sound: Then have them chase you when you make sounds, maybe they are sight orientated: Make them chase you when your seen, maybe they have terrible eyesight: Okay, they only notice you when your close, maybe they have super eyes: Okay, they will notice you from far away. I think you get what I'm saying.
But right now I'm trying to ask what would you guys think of this. Is having monsters visible and on the map and I don't know, maybe they'll have random chances of even showing up plus having them have different ways of sensing okay? Too annoying? Kinda too much?
