I only know a great deal about World of Xeen which is part 4 and 5 combined into 1 game. Its dated but wow, I have played this game thru so many times since I picked it up as a kid (still got my CD's). The characters are voice acted which is nice for its time. The worlds are both huge grids that you will want to explore every inch of. The puzzles in this game are creative and the difficulty of both the puzzles and the mobs is quite challenging. The atmosphere goes from light to quite dark but retains a feeling of enchantment and charm. If you don't mind (or like) retro graphics, shutterstep grid-based movement and a huge challenging world(s) then this game is worth the money for the pack by itself.
