I replay them every couple of years on average. I'm shocked every time by how well they stand up still, and how good the atmosphere is.
Well, other than the ill advised zombie killing levels

You're right though, Thief is still a classic today. I do really wish that they had done a proper, faithful reboot with modern tech because there are rough edges but that doesn't stop that deep warm and fuzzy sensation that you get from sneaking around.
