I cannot judge the game for you. I can say that it is pretty easy to learn and you can quickly decide if it is worth your time. The user interface is much friendlier than MNO, so you do not spend all your time fighting through it.
My biggest complaint with HUCE was the "Bitchin' Betty", that you could never turn off and it would not shut up! However, supposedly, that is now a user option (but I am not certain if it is officially in the game or just more untested Beta.)
In the distant past, HCE was always one of those games where you wanted to play 'just a few more minutes' and end up seeing the sunrise.
