The Stanley Parable
I’m a huge of fan of Half-Life singleplayer mods. Every once in a while I browse ModDB.com’s popular HL2 mods and see what others are enjoying.
And this morning I played a unique mod called: The Stanley Parable.
I won’t go into detail about this mod. I can’t go into detail about this mod. The reason is because this mod needs to be experienced with as little information about it as possible beforehand to enjoy.
But it’s really really really good. Check it out if you have a chance.
Does not require Half Life 2, only the Source SDK.
I just played through this as well (several times, of course). The less one knows about it going into it, the better.
I highly recommend it and I highly doubt you will like it. Or, at least, how it will make you feel.
