I did not know the GOG version is easier to mod. I bought the whole pack last year when steam had it on sale. Was nice revisiting an old game. Thief 2 is still the best pure stealth game ever made. I am now interested in playing T2X and I got it to work but the movies won't play. Hopefully I can solves this.
I really hope they are gonna keep the same art style for the cutscenes and for the love of all that is holy, keep the same voice actor for Garrett.
