The new thief game, as someone who never played the old ones, was a good stealth game, but from everything I've heard about the old ones it was only a decent Thief game.
Also, got fallout 4 yesterday and it's pretty much what I expected as far as game play goes. Settlement building is a bit more complicated then I thought but enjoyable.
I agree, Thief was a good stealth game, but yeah, As a thief game it wasn't really on point. Actually, I can see it being better if the main character wasn't Garret and he was only mentioned in conversation and/or lore bits you find. I also wish they would have stuck to the old thief's theming a bit closer too. OH well.
There are some mods you can get that improve the base building by adding more stuff you can build, try to get a hold of some of those.
I never really got around to playing either Thief game, but from gameplay videos I watched I noticed that the main problem with the new Thief is the fact that it was only "Thief" in the title alone.
In the original Thief you played as a charismatic sneeky-beeky lad thrown into huge sandboxes to sneak and steal your way through. The new Thief was structured more like Dishonored, which isn't bad mind you, but Dishonored was structured like that because it was more about assassination. Even then though, Dishonored was a better Thief game then Thief(2014) and that was probably because Dishonored was made by the guys who did the original Thief the Dark Project.
