Calling sonic.exe and JTK tradition is not a good idea, yes, there are good things made out of them, but the original story's were...well...they were not that good :( (at least they provided you a good spook during the night)
I'm more of the 2010 horror games as well: FNAF, the Outlast series and Slender: The Eight Pages. I do find Poppy Playtime interesting tho. I also found Evil Nun interesting as well for being a mobile game and a copy of Evil Granny
