Like others here, I remember when it was offered for free on Blizzard/Battle.net's website. The Lost Vikings was a great puzzle game. It definitely deserves to be remembered and preserved. I just hope Lost Vikings 2 can also get remembered. It reminds me of Gobliiins, where each Goblin has 1 special skill. The Trine series, Trine 1-5, also have 3 swappable characters with specific skills to solve environmental puzzles.
