There's also The Secret of Monkey Island game for Sega CD, plays sorta like Willy Beamish.
As for The Space Adventure: Cobra-The Legendary Bandit, this is similar to Snatcher, except it was much more boring. It has good parts but their is not much interaction. Snatcher had shooting parts, some areas that you had to guess answers to puzzle questions, and input phone numbers. Doesn't seem like much but take that stuff away and all you get is a book.
Remember how frustrating it was to keep repeating certain comands so something new would happen and further the plot in Snatcher? Now picture that in Cobra, without the extra interactive stuff. The only part where you get to actually interact, sorta, is a puzzle toward the end of the game. You have to put some different colored crystals in the correct order so you could proceed.
I didn't mention the battles because you don't control anything there either. Its a roll of the dice. Pick a command and Cobra does it, and then its a roll of the dice if the enemy gets hit by it or avoids it, and possibly counterattack. You just sit back and watch what happens when you pick an command option or Punch, Kick, Psychogun, or Flee. But I do have to give thumbs up on Crystal Boy. There was an interesting villian. And it felt good to finally off him, using an unorthodox attack.
