I was just cleaning out my computer of old and unuesed things manuely and i found a game in system 32 and many others in the Windows folder. Thoses are not for games those are for windows thingys so i think that installers should have to install to Program files for it to be posted on the DC.
Half the games here on DC dont even deserve an installer anyway, even the good ones should be put in zip files. Only games that should be put in installers, are games that are large enough to need to be compressed in an installer.
PS: If I'm not mistaken, the games are are in System32 are games installed with the default TGF installer... shame that wont be changed & a double shame that all newbies feel the need to use it all the time.
I believe zip does have a better compression ratio than an installer. And it doesn't has the overhead an installer brings.
But, if zip isn't small enough, try 7-zip.
