I think Act 1 is probably the better game but Act 2 had what I wanted after Friendsim, which is more of the cast of characters it built up. I think if I hadn't read or cared about Friendsim that Act 2 wouldn't really have been as enjoyable.

If you haven't you should check out the LucasArts point n click games, with what you liked about Act 1 I think you'd have a great time with them!
