Browse Game Database in Wordpress

I have a Custom CMS running next to Wordpress, with which I manage a Game Database. Now I want my Users to be able to browse a Game Database and view single Games, with SEO Urls, WITHOUT "importing" all Games and WITHOUT managing the Games within Wordpress. Means, I want to keep my Custom CMS to manage the Books, Wordpress only needs to grab the Data from my MySQL Database. So technically, I just want a page, f.e. "[login to view URL]", which gets the vars needed (pageNumber, keyword etc) via mod-rewrite, to show the games out of my database. Then I need a second page, f.e. [login to view URL], which gets the game id out of the mod-rewrite url and then gets the game data according to the Game Id, out of my database. The mod-rewrite rules are already defined in my current Custom CMS, we just need to get this working with Wordpress. Overview - create a page to browse game database, stored in non-wp tables - create a page to view single games out of the non-wp tables - non wp-tables are in the same database - the two pages must get their needed vars (game id / page number etc) via mod-rewrite (SEO Urls) - I dont need these pages to be "designed", only simple data output, i will do the rest :) - your code must be commented, so I can understand it, in case its "ugly" ;) If you have any questions, feel free to ask!
