In Meridian are merchants for every type of artifact. Didn't finish them all yet though.

Yesterday I finished The Park, was ok, got it for cheap, was through in one hour. The setting is nice, I mean who would not be scared in a dark and eerie amusement park. The game although lacks in jump scares, perhaps one or two during the whole playthrough. The end has something scary, well done, but there's not really happening anything around. If you get it for cheap, try it. I paid 3.99€ instead of 12.99€.
I also played Neverending Nightmares, which has a nice artwork, in a way that it is different, like drawn with a pen, black/white with some red thrown in for interactive stuff, but after just 30 minutes I got quite bored. The game plays a bit with your mind, as it's about mental illness, but running through doors and corridors which are all similar, gets tedious after a while. I paid 4.99€ instead of 14.99€.
I also tried Tearaway Unfolded, as it was for free for PS Plus members. I had already my doubts, as I'm not the biggest fan of such games, but thought give it a try, as it's for free. But it's definitely not for me, already the artwork, which I admit is very nice, but I prefer a different style. Cannot tell so much about the game itself or gameplay, as after only 20 minutes I deleted it again.
