Games contain the platform:shockwave-flash tag

platform: The operating systems and platforms offical supported by the game

shockwave-flash: The game requires Shockwave Flash (Adobe Flash Player) to run. In particular, this tag is only used for games that are distributed with `.swf` files. This tag should not be used if Flash Player is bundled with the game package (e.g. Adobe AIR). All games that use Adobe Flash technology should use `misc:adobe-flash`
