Advice on using Custom Post Types

I have 8 custom post types for a lottery website I am currently working, one custom post type for each game that is in the lottery, but I am now wondering if this is the best way to go about this, would I be better off do you think in creating 1 custom post type called draw results, and having all the games results in this one custom post type, and then have categories to select for which game the results apply to, or should I stick with the 8 custom post types, and list them under a game information page in my menu as this is how I currently have it setup.
