Obviously accuracy matters in the general sense, better aim = more hits scored = enemies die = you win. But a lot of games don't really reward accuracy other than a badge or achievement, and spray-and-pray is a legitimate tactic.
So I was thinking, what if you designed a game where accuracy was really important? For example, you LOSE points for every shot you take. Shots that hit an enemy are neutralized (-1 point to fire the shot, +1 point for hitting an enemy), and then kills are something like +10 points. So getting kills is important but so is getting them accurately and with fewer shots taken.
Ok, not earth shatteringly neat or anything but it came to me today and I thought it would at least something neat to try. Players run around like crazy and fill the air with lead. Seeing them really set up for a shot because missing has a bigger impact would be kinda neat.
