One thing that makes a game really fun is a highly customizable difficulty level. This usually allows novices to jump in and have fun while offering a more difficult challenge for experts.
Silent Scope offers eight different difficulty settings, but they all seem to start at 'hard' and go up from there. Now - before you start it with that smirk, understand, I consider myself to be a pretty good game player. Further more, I'm not bad at this one in particular. In
Silent Scope, I have knocked down the Harrier
TM once with just two shots, actually sniped the @$$h*le running through the stadium with the President's daughter... but the difficulty of the game really does ramp up in a fairly ridiculous fashion.
You can get extra lives here and there by peeping on young women in bikinis, but it seems that more often you simply run out of time. And, should you wish to argue that I'm growing slow, I'll point out that I sometimes don't even drop into the scope view (which moves much slower than non-scope view) to take out terrorists... cap them in one or two shots, then it's on to the next one. The controller only allows you to move at a certain rate of speed and maintain control. Perhaps if there had been a special controller that made up for it, that came packed with the game, it would have been easier. But as it is, you have to be extremely dedicated to this (one) game to progress. In my opinion, the reward doesn't make up for the difficulty.
