one of the very few things i found very lacking in torment is the few numbers of weapons, i know some might think there were a lot but theyre werent really, many of them were just upgrades of a previous one and all the good weapons had certain things needed to use them (i.e. celestial fire, lawful good). i just think that there could have ben more diversity for the weapons and more of them.
and the spells, the effects were brillaint and the little movies for some of them like the abyss were amaxzing but yet again there were no really good spells and not many of thema nd yet again the unique spells only appeared like once and it meant you had to decide between dak'kon ignus and namless one for who to teach it to, i just think that they could have included more spells and some of the best ones could have shorter movies because lets face it, when your mum tells you to get off the computer before she threatens turns it off and ground you for a week and the worst thing is you just casted celestial host! see what i mean?
just my two cents.

You could throw Celestial Host on her... ;)

Anyway, the main plot in this game was put on the story and characters - not on hack and slash. Movies, number of weapons, spells, tattoos, etc. don't ruin the gaming experience. And that lack of variety can actually make you forget to search the right items/spells combo for use and to place your attention on the story itself and NPCs. That's why I love this game.

is there a sword animation for the nameless one in the game?

Can't remember, try Celestial Fire to see it(but of course - you are not lawful good ain't you).
