@Hvinire, please just make it an option

If it's a problem with PS3 capability, you -can- make it a PC only feature... you can make it spatial (they only popup within a certain distance of your periphery) & cap it (only so many on screen at a time; only so many characters in a bubble).

1) easy to implement, 2) it's already in the game for NPC's you walk past, 3) it can be defaulted "OFF"
