Definitely a 'Prologue' (introduction) to the Talisman Digital Edition. Consider this to be a tutorial to the extreme, enough to be able to sell it seperately.
I consider it more of an occasional distraction, probably not one of those games that you feel like playing for hours on end...but one of those that you 'pull off of the shelf' here and there.
After playing Talisman Digital Edition, I will say that I did miss the quests. Ultimately, it could be cool to blend the two and introduce individual quests into the Digital Edition.
It seems that, at the least, Prologue will either be a quick distraction, or it will be one of those that you will enjoy here and there. (Obviously there is the possibility that it may just 'click' and it is played to completion).
In other words, for the price ... not too bad. I enjoyed it so far, but for me it is here and there. It would seem hard to go wrong if you can get it in a bundle or, as currently under a couple bucks. (I'm buying a couple extra as gifts ... can't go too wrong for that price and maybe they will go for the Digital Edition and we can do multiplayer...)
