I put this into the code:
<table><td>
A cool game called "Thing Thing 2"<br/>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="640" height="400">
<param name="movie" value="http://ar3s.com/wordpress/wp-content/themes/ar3s/games/game.swf" />
<param name="quality" value="high" />
<embed src="http://ar3s.com/wordpress/wp-content/themes/ar3s/games/game.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="640" height="400"></embed>
</object>
</td></table>
...and when it didnt work, i hit edit, and came back with:
<table>
<tr>
<td>A cool game called "Thing Thing 2"
<object width="640" height="400" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
<param value="http://ar3s.com/wordpress/wp-content/themes/ar3s/games/game.swf" name="movie" />
<param value="high" name="quality" /></object></td>
</tr>
</table>
EDIT: Holy crap! it opens properly in IE
Now to get it to open in FireFox >_<
