Aw come on no need to be that harsh...
firstly you can save your game anytime, anywhere which most games haven't managed to do very well (not even GTA).
This game has the splinter cell feel to it and has very good graphics for a psp game. controls can be a bit awkward but i thought you can get used to them easly and they wasn't much of a problem for me.
Sound wise is good, it has all the useual cool splinter cell gun sounds and sneaking sounds and easedropping on guards conversions is fun.
Some levels are dark but that deosn't matter get over it!!
I suppose one let down is it does have quite long load times.
To conclude I would say the first splinter cell game for the psp looks and plays good and has the fell of the console versions.
Harshly judged by some people...
