For me, it's a timeless classic. It's a shame that there is no successor for this game, because it was such a unique experience, that to this day, there's nothing like this. And also it had official Hungarian dub, which made me fall in love with it even more as a kid.
The game made you pre-plan, and expected you to think of better ways to do something when you made a mistake.
For example: sometimes, a good that you have to steal is periodically checked by a person, and if they find out before you leave the place, you will fail. this forces you to think.
This also applies to doors, and other stuff.
And lastly, the sound. Every equipment you have on you has a threshold, some are quieter, and some are louder, which forces you to be careful when you use it.
I could go on all day, but there's so many things in this game, I don't think it would fit the 2000ch limit.
This game, though it has MANY bugs, is FANTASTIC.
It's a shame it doesn't have digital releases anywhere, even physicals are scarse. That's why I want it on GOG.
