here's a suggestion - make weapons tilt when aiming down sights
i did some experiments and it works really well:
gangstajust simply add rotation = eulerToMatrix( "0 -20 0" ); to every ads image and you get great results
with this feature, you can tell if a sniper is scoped in or not, allowing you to safely flank him with the knowledge that he's distracted
you could also intimidate your opponents (as shown above) gangsta style
and i guess it just looks cool in general
one slight problem is that rotating the gun while its bipod is deployed does look a bit silly
