The first Deception game by Tecmo. A pretty basic game in concept: Invaders come in your castle, you set up traps, lure them into the traps. But- Something about the limiting view of first-person, combined with the poorly lit castle, chilling music, and dark story tone has never been replicated. Add on how you could customize your castle with extra hallways and rooms with special attributes, capture invaders to make your own monsters, or even use masks to change the way invaders react to you... mmm, now I want to play it again.
I tried playing the second, third, and Trapt, but everything after the first game switched to a more action-oriented third person view and started to shy away from the heaven/hell connection.
I wouldn't mind if it was a game outside the Deception IP. I just want the atmosphere back.
I own Deception 4 on PS4, didn't know what the original was like. I think there's a lot of cartoony appeal in luring people into elaborate multi-stage death traps, but it's tricky to garner appeal out of more than just a lot of animation work for each variety of trap.
