There was nothing like staying home sick from school, dialing up to one of my favorite local BBS's, and waiting a few hours for the Commander Keen shareware version to download. The game was great and the first episode had some pretty sweet PC speaker sound effects. This was definitely an underrated side scroller. Action packed, challenging, and kept you wanting to play more. It's no Doom, but we're not even comparing the same kind of game here. Simply holding the [G] [O] and [D] keys at the same time enabled God Mode. Can't beat that. And that super jump that allows you to pretty much float across an entire map was also pretty bad ass. Can't believe it's already been 20 years.
