People might not know this, but how do you think console games were patched before consoles could be connected to the internet. Trick question! they werent!

Not to say they werent patched at all, they were but the only way to get these versions were to buy the game all over again. Games had alot less bugs back then too, all of them were minor and none of them were game breaking. Times have changed so much now, game developers would never be able to get away with the crap they do these days back then.
Yup! Absolutely right.
But keep in mind that modern games are way more complex than the games of yesterday.
More complexity, more bugs.
And online multiplayer didn't exist in the 80s...
