i can’t open this file because it’s in 7-zip format.
i mean: i can, but there are many other games to play too, so putting them in a harder-to-open format drops any Internet Download down my priority list very much,
which means that i may eventually forget and never play the game.
the other formats like 7-ZIP or RAR or TAR or TAR.GZ or TAR.BZ2 are great for these people who want a smaller download and already have the special program for it,
but you must At Least have ZIP, which is the only one of those types that already works with every system that you don’t need a special program for opening.
