I've got Trials and Tribulations in my closet. I really want to play it but don't want to start with the 3rd game in the series. If I come across the first two I'll give them a try.
No, you should definitely play Trials and Tribulations first. It's actually a prologue to the first two, so you will enjoy it! I played Trials and Tribulations first as well. In my opinion, it was the best game.
