Holy smokes! 500mb? I had to re-read that a couple of times. Personally. I wouldn't even want to install a 500mb game, let alone trudge through one. Total Chaos clocks in at somewhere around 20-25mb and that game plays like a dog on anything less than an 060.
And the hundreds, if not thousands of games on that whdownload site seems to be around the 3.5gb range for ALL of them. I bet that's how the guy is judging a systems software library though. Sites like that *must* be complete, no? lol
I use to play Total chaos in an "ordinary" 030 @50MHz (128Mb RAM). OK, was not a speed demon, but works!:)
