What's the difference between Schizm II and Uru: Ages Beyond Myst? Answer: one is a graphically lush adventure filled with a pseudo-futuristic hippy plot and obtuse logic puzzles. The other is... Erm, exactly that. Damn.
But hang on, there is a difference. It's the difference between a game that I'd recommend playing to anyone interested in intellectual stimulation and a game that's called Schizm II. Basically, while obscure, the puzzle content in Uru does at least gel with the game's carefully constructed universe. The puzzles fit.
In Schizm, you're given puzzles purely for the purpose of breaking up the lengthy FMV sequences telling the (admittedly quite intriguing) story of two tribes at war. Some may ask: "Why's everything gotta fit?" Because that's how things work, you idiot. Schizm II just doesn't fit.
