One mustn't download the maker, actually.
But you'll find the English version at http://www.google.com !

Hm, how to create a good game?
Just... work a lot! No, u need a good story, that's the most important thing of a game. Then you have to "tell" your good story, this should be made like a mystery or something... at least the beginning of ur game should make people stay playing it.
And I think that it doesn't matter whether u take the maker 2000 or the maker 2003. The maker 2003 has got a few features the maker 2000 doesn't have, but practically there is no difference between them.

Have a nice day!
