I never played Hotel Dusk either but Theresia is so addictive its insane. I love the game crappy hallway graphics and all. I noticed several sites mentioned it being like Hotel Dusk so I am going to poke at it a bit just to see; I'll be certain to bring in the verdict on that. Theresia has been around for a year now and has so little information on the game that it just blows me away. Any survival horror junkie should give Theresia a try, for it won't depress you like Resident Evil: Deadly Silence did. On another note it looks like Work Jam released an iPhone/iPod touch version of the game earlier this summer titled "Theresia... Dear Martel" which as soon as I raise the funds for one of the suckers I'll be getting just so I can see if it is anything like the parent game, even less info on this version and it seems like it focuses more on the second story in Dear Emile.
I'll stop ranting now. XD
