I just started to think about 3rd person stealth games. There is not many of them: what I have played and what were enough good to be remembered was.

- Metal Gear Solid series
- Splinter Cell series
- Hitman series


what else is similar for those is that the maincharacter is charismatic character who has his own "little" problems. That's why we all can identify to the atmosphere and really enjoy the gaming experience which is crucial for good game
Also all of those games have potential to develop the story that interest more people than just people who play. Even people who like movies will start to play these. I hope that games will develop the feeling for even further to get more people join the wonderful experience.
