The first Splinter Cell I played was on an old cellphone. It was a side-scroller with colours and stuff, so it was a pretty big deal back then. I was terrible at it though (maybe because I was at most in first grade).
I haven't fired a rifle in ages and my eyes are going bad. That said, I can still reasonably hit targets in light gun games like Silent Scope. My operating ranges would probably be a lot closer than Sinon's, though. Probably 700-200 yard ranges (assault/battle rifle ranges).
