Until Dawn is an interactive story based game, kinda like Fahrenheit/Indigo Prophecy, Heavy Rain, Beyond: Two Souls, and many of Telltale's series like Telltale's The Walking Dead. The setting being like a horror movie with 8 teens going to a lodge only to be terrorized and they have to survive until dawn, and it is better than it sounds imo. You mean PSMD X3, and I know how it feels. It feels like forever just to get it.
In my opinion, BioWare makes some really good RPGs. My personal favorite is Mass Effect, however Jade Empire is dear to me since it was the first game that I ever completed ever and the first game that I was really into.
You should play them because you got them for free XP
