- refer to http://jeuxlibres.net [fr] to find libre games (if some are missing that are really libre, well suggest them in their forum )
- check http://liflg.org/?catid=6 for games with loki installer (all data may not be free)
- check http://www.cheeplinux.com/product_info.php?products_id=389 for a list of games previously included in knoppix games edition
- have a look at working games with Mandriva http://qa.mandriva.com/twiki/bin/view/Main/Games
Remember that only those already packaged and with a libre license will be included. Another detail : the XDG menu is compulsory so be ready to repackage and submit to blino before hoping that it can be included :p
BTW blino's current list is http://blino.org/blog/mandriva/games/in_the_game.html
Feel free to add below those games that you know are packaged, work with 32 bits architecture, have an XDG menu (but do not expect they will be taken into account :p).
