You are right that you will never get anything near as good as Crysis if you start from scratch with Blitz3D or something really simple. If you try to write your own system you will end up spending years on it. I happen to like engine design better than games, so I am happy with it. But if you want to make a game, you should use something that gives you a foundation to work with.
Crysis is a very neat combination of good tools, good art, and good programming. I really like the Sandbox editor, and it reminds me a lot of Garry's mod for HL2.
