my favorite hack is light platinium, the maps are great and I really like the storyline and also the tiles, it's on of the only hacks I played till the end
then it's mistycal, the second hack I played till the end, the story even better than of light platinium, but there's still something that majes me like light platinium more^^
then the third is onyx blue, the storyline isn't changed, even the tiles aren't changed, there are only a few new special events, but the maps of onyx blue are just the best, the creator of onyx blue is the best mapper ever!
of course it would be better if he'd change also the story and the tiles and so, then it would be maye even before light platinium in my list but well.......
