I don't think I ever won a single joust. But I once managed to kill my opponent's horse.
Anyway, about worst endings :
- Arcanum : the whole game tends to be disappointing, but the end is especially lame.
- Icewind Dale : I hate IWD ; the fact that they inserted Crenshinibon in it only made it worse (what is it with D&D CRPG and Salvatore novels, seriously ?) ; also, Balhifet ranks among the least interesting villains ever.
- Anything from Silmarils : they just couldn't be bothered with actually giving their games real endings.
- MM 6 : Yeah, I just blew up a random demon base ! I really feel like I accomplished something !
