I was happy to see this pack for sale. I was especially excited to see that it included 'Might and Magic Book One: The Secret of the Inner Sanctum'.
It seems many reviewers haven't played this game. That is too bad. If you haven't played it, I suggest you give it a try. Sure it uses very dated style, but then this was one of the predecessors in the field. Other great games like 'Eye Of the Beholder' and the latter (V, VI, ..) 'Ultima' games get a lot of attention, but I think if you give MM Book 1 a little time you'll find there is still a shine to this old gem.
Keep it up GOG, you're doing an awesome job!
