Tree of Tranquility has its high points, but it's far from the strongest entry in the series. Many of the game's shortcomings can easily be overlooked by players who are giving the franchise a try for the first time. However, those who've faithfully stuck with the farming sim over the years will find this latest entry offers more of the same. There's simply not enough new material here to warrant a new game.
Bottom line: There's too much recycling and not enough substantial improvements. The series' staples are here and enjoyable, yet innovation is missing.
Recommendation: Tree of Tranquility is worth buying if you have the time to leisurely wade through all it has to offer. Still, don't be surprised if you find yourself tempted to toss it on top of the trade-in pile.
