How do I use Anti aliasing in the game enigne?

I saw tons of threads saying it’s not possible, but they were all from 2004 and 2006, and I really doubt blender wouldn’t let you use something so essential in the game engine.

blenderplayer.exe -m 16 blend_file.blend

on new versions of 2.5x bge
anti aliasing level here is 16

Could you be more specific?
I don’t even know what you’re talking about.

it is the command line that you must use in order to use anti aliasing. Use blender.exe -h for all the infos

Nevermind, I’m tired of fighting with the blender game engine.
I’m going to use ogre for games from now on.

… How do I export .mesh files from blender?
The only tool I found is for 2.4
