The grande thing about mobygames was the database search. It reminded me of the movie "The Fugitive" with Dr.Kimble aka Harrison Ford: You would search for something, displaying the result "2000 results found"
Then you would add "show only isometic", which would mean, displaying the result "140 results found"... and so on. Everytime you specify a property, the results would narrow down until they become managable, and so on.
"now only 12 results remaining" and in the end you see, there was only a detailed view for the results that matched. Damned that this is gone! FFS!!!
