The first 'six' I encountered in a mainstream game was in an Ultima 6 (or 7 I can't remember) at the town of Cove IIRC, twas reasonably within bounds of good taste, 16-bit graphics don't do much. Next was Deus Ex, where one could hear some 'activity' in a locked off room. The most Oblivion ever did was through the books and not much of that, as well as the name the Anvil quayside boarding house. Bethesda can go farther without going beyond good taste. PG13 taste anyways.
Yes they could, and sixual references are fun... But I mean, come on... Whether it would be implemented that you could actually have relations with NPC's or not it would probably be something like "Interact with girlfriend/[censored] victim - > Have six" and then you could watch a 10 second animation of pixel sodomy... Why, oh why would anyone want that in and Elder Scrolls game?
Sorry I forgot to multiquote, but someone further up talked about wether bruises, cuts, and more blood was needed so...
No, it is not needed. In fact, I'd be perfectly happy with a game completely identical to Oblivion in engine and graphics, but with a new setting, storyline etc. But now that they've gone ahead and developed a new engine and there is a thread asking wether or not I think it would be a good idea to have more blood in it? Yes, I think it would be a good idea. The whole idea of developing and, hopefully, improving an engine must be to make it look more realistic. And I think, a bit more realistic combat on the visual side would do some good there.
Not talking about organs and blood splattered on the ground or being able to do a Monty Python and chop arms and legs off a dude and leave him to rot, but a bit more blood and perhaps some visual cuts and bruises would be a nice addition.
