Clearly this is not my kind of game, but I can say it's worth your money if you like stealth games. Playing with mouse and keyboard or with a controller doesn't seem to make some difference, aiming is difficult in both cases. I don't have that many reasons to keep on playing it. Lucky for me I got it for free.
It's old, but that's not the problem. I sometimes like the old ones, when they are well made. But this game has a ridicolous combat system, and gaining exp is frustrating even when you start. Play it if you like spend hours and hours in grinding.
The first one of the serie I played. Because it's not that hard, if you play it at "normal" difficulty. Frustration is far from it. Progression it's easy, two or three level up will be enough to beat the next boss, that's a great thing if you don't like grinding for hours.
