The Office (Episode 2 v0.3b) is very much a porn game, not only in the amount of sex it has but also in the way it treats its story. Thus, characters are rather flat and sexual encounters of different degrees abound with most choices revolving around having or not sex (or sensual interactions) with certain characters. It is direct in this and honest, not working much on the buildup to scenes and so on. I personally find that a bit off-putting, but I guess that is up to everyone's tastes.
Render quality is pretty high, as is the models they use. Animations, on the downside, are pretty basic and poor, and many of them run for too long. And, as far as I've seen, there seem to be no sound effects or music of any sort.
All in all, it's a decent game, but probably won't be able to go beyond that.
PS: it's been recently updated with The Meeting, a short independent story. I don't think it's much worth it, but in order to make it clear, it's an independant story. Like christmas specials some games have.
PS2: this edit comes after the Ep 4 v0.1 update, and the game has continued falling slowly down the cliff. As time goes by the content comes out slower, more bugged and with more problems, sex scenes still have rather poor animations, the gallery is terribly bugged, and so on. It just went from 3 to 2 stars for me, and I'm considering dropping it.
