The description should read: "Build Your Own" Even with this AdOn EA has splashed out and supplied all sorts of class bugs. If it were not for the resourceful hobbyist Communtity (which should be slowly paid time EA) this would probably forever unplayable, since even the bugs that have been there since "World Adventures" not resolved by EA! For me, this series has done, have given enough chances EA and bought faithful over again, but rather than fix old bugs with each AdOn always new dazuzubekommen is just naughty.
... Oh, and the Hadbuch saves EA yes now also / the bugs were probably too expensive.
Conclusion: as always a great idea, only the technical Umsetztung "failed" (Defective goods you are usually back) 1 point for the shell, stable and without visible defects!
