Nice filter. Edge tracing?
No idea about the game....

Yup, that's the one. I like the artistic impression of it while it still retains enough detail.

Next image will probably give it away to those who played the game.

Is that Wanted?
Edit: By that, I mean Wanted: A Wild Western Adventure, also known as Fenimore Fillmore: The Westerner in Europe.

Nope zeogold, that's not the right one.

Here's another filtered image of the game, it is a very common sight in it:

syberia?

It isn't Syberia either.

One more pic:

"The ABC murders"? (based only on the assuption it's the '30s)

It looks somewhat familiar but I'm using a phone now and can barely see what's what...

It's not but your assumption is right, you're very close to time period of the game.

I'm posting an edited last image if it helps:

Wild guess on those floors
L.A Noire?

Nope, that's not it.

Either taking the colors out takes too much info away, or the game isn't that well known. I'll try with a few more filtered images and if there's no correct answer I will post unedited bits later today.

Now I'm on PC so it's a piece of cake. Even the first image would do. I just couldn't see much on my mobile phone.

Dracula 3: The Path of the Dragon.

That's right! I thought you might recognize it since I bought this game based on your recommendation.

Recently I've been at this game in the evenings and it's quite interesting. As a curiosity, so far amongst the literature in game I have discovered what appear to be complete copies of Bram Stoker's novel Dracula and the Bible in Latin.

lol ! yesterday after Syberia I've checked Dracula 4, 5 and Dracula Origin (the only that I've played and completed) but not that one!

now the new hint, the romanian flag, was a determinant clue.

Ouch you were close - or better - on the right path. :)
