No, the fact you cannot see the endings doesn't make me happy at all - OTOH, the other fact, that a cheat failed to work does. Even if it means overcoming a problematic/buggy point in a game, cheats just make me upset.
I've never used cheating in any other game, and before IWDII, I had the exact same opinion as you, but that game maked me want to kick the crap out of my computer, and cheating saved my little cabinet from being torn to pieces.
The interesting fact was, I didn't complete the game anyways. Too many bugs for me.
