Well I really really enjoyed playing Prince of Persia 3D so another one of those would be great.
All the Might and Magic (except 9) were great.
Mist and Riven were good and Mist III was just OK.
I loved Land of Lore-Gardian of Destiny and also Star Ship Titanic was a good one.
The Journey Men Project had Author who was very helpful and funny
I find it hard to pick out games today and not knowing what they are going to be like.
This is why this board is such a help with that.
They don't give you very much info on the box.
