NWN=KOTOR=JADE EMPIRE=MASS EFFECT (cant comment on BG, haven't played it, I was too much of a Diablo retard at the time, although I would take Diablo's straight action, bland story, no character relationships over Bioware's attempts into "epicness" anytime of the day.);
Plot:
NWN: find the ancient lizard people (through teh words of powah!);
KOTOR: find the ancient star maps;
Jade Empire: find the all pieces of the amulet;
Mass Effect: find the ancient technology artifacts;
Romance:
NWN: Aribeth and male player character (or that other guy under Aribeth's orders if female PC);
KOTOR: Bastilla and male player character (or Carth, under Bastilla's orders if female PC);
Jade Empire: Dawn Star or Silk Fox or both if male PC (or Sky if female PC);
Mass Effect: Ashley for male PC (or Kaidan for female PC or Liara for both);
Homosexuality:
NWN: Aribeth declares love for the female PC even though no actual romance occours;
KOTOR: Juhani declares love for female PC;
Jade Empire: hell, this one is rough. You can have a "Ménage à trois" with male PC and two female NPC's (

Mass Effect: alien lesbian sex
I'm not even mentioning the same stupid plot twists that happens on all games in exactly the same manner and everyone claims "wow I NEVAH SAW THAT COMMIN!!11!!" or the fact that the main evil guy is nothing but an egomaniac that wishes to lay waste to the entire universe for no reason at all other than looking badass, hell, he doesn't even want to rape the cover girl (Aribeth/Bastilla/Dawn Star/Ashley) but instead wants to convert her into a tool of destruction only to have her betray him at the end.
I could go on but it's tiresome (and painful to my brain) to remember stuff from all games that are EXACTLY THE SAME and biowhores salute them for "innovation".
Oh damn, I forgot to add the most important stuff about bioware games, the dialog options:
1) :D
2)
3) :twisted:
