I have been wondering about this. In the show, the scouter's quickly became obsolete after the Frieza saga, then were incorporated in a limited way into the android and cell saga (the androids had built-in scouters I remember.)
However, they are not as useful as the "sense" all the chars eventually got. Somehow they could slightly sense incoming dangerous attacks because of the massive amounts of power in them. I think the game should incorporate this in a limited way by goving you a tiny indicator on the screen somewhere that flashes red when a really powerful attack is heading towards you or something. That is kinda "realistic" so to speak. If the scouter by itself reads power levels, then it should sense the power of incoming attacks, so at the very least attacks should show up on your radar, maybe as a different color or something. Just an idea, really, but it would be very convenient. Anyone else got any ideas similar to mine or something?
