hmm, and thats a reason to take up an old topic?
Well, this is. I was thinking over this one a lot and I've thought that maybe you could have more animations, say for picking up paintballs, etc. Or having slightly transparent hoppers and having it so that you can see the pballs in there. And having different gun models things (shown on your 1st person HUD, but actually on the gun) of things like hoppers, barrels, CO2, etc.
