Lying to the player about the game length ? Hello, in short : is there any con against telling in-game the player will have to do 8 levels to reach the end of the game, but actually having 15-20 levels ? (but the game information on website will tell the real number of levels) in long : I'm currently creating a FPV Dungeon Crawler (close of Dungeon Master). It's party based, and during the exploration, the party members will talk to the leader, which you incarnate. You're running after escaped prisoners, starting in a prison deep into the dungeon. As you're making your way up, 1 of your companions, who has some basic knowledge of the dungeon, will tell you when you arrive in a new level, letting you know how many levels are left before you reach the exit. Just before you reach the exit, you'll meet the big boss who will talk to you and teleport you to a level deep down in the dungeon, unknown to anyone, so now your companion will have no idea where you are. So my concern is that I'm going to build up a feeling of "we're almost there, even a bit closer, yup, game is almost done", and boom, big unknown, no idea how long the game will be anymore (except if you have read the detailed game description and its feature listing ). Would you see any problem to that ? An alternative would be to let the player know is on the "final" level only when he reaches it, or when he gets very close of the exit. It'd still give some strength to the surprise, while avoiding too much build-up to the possibly frustrating deception. my opinion (read it after you have made your own! ) : as a gamer, I often like to know how far I'm into the game, and I begin to anticipate & root for seeing the end of the game as I feel it's approaching. So I'm not sure how I'd react if when I just thought I had finally reached the end, I was getting thrown in the middle of nowhere. It could be quite frustrating. On another end, if I still didn't have enough of the game, I'd be relieved to see it's going on..! Thanks in advance for any thought on that matter !
