What's good about the set:
- cheap
- the solo adventure does an excellent job of easing a new player into the 4e mindset. I was a hater, had dropped out, this brought me back (though only Essentials). It also teaches the basic rules very well.
- production values are good
- product is clearly written and engaging
What's not so good to bad:
- the solo adventure has to be played four times to make four characters. This has to be done before the group session, so the book has to change hands four times (getting five people to each buy this set is absolute overkill).
- lots and lots of mistakes in the rules. Examples contradict the rules text (which is generally correct). This makes the set look sloppy and is needlessly confusing for new players, especially those new to RPGs.
- the group adventure is blah - clichéed, too hard for newbies, hardly any opportunity for roleplaying, the villain is just there to be killed... Plus the entire dungeon has this (bad) old-school static feel, where the monsters/opponents are standing behind the door waiting to be killed by the PCs.
- the characters you make do not correspond to the characters you make when upgrading to the Essentials books. Once again an incredible oversight/mess-up.
- Only two levels are covered in the set - which means that its usefulness will be over at the end of the group adventure, more or less.
So, WOTC dropped the ball on this one but got me back on board nevertheless...
