It isn't everyone's taste of games, even I grew tired of constantly having to sneak around.
So I followed up sessions of Thief DS with more action oriented games to alleviated that.

And yes, the last game in the franchise (though it can not be called a sequel as it is so far distanced from the original games in lore and gameplay) has quite some negative reviews and fan reactions, for one the increased linearity and some of the bad game design choices, some of which were already present in DS.

But it is nice to play just for a different setting when in general I only play sci fi games set in the near or far future.
