My little sister has been playing a few Mega Drive games, and I'm glad she can't play most of them because she doesn't know the "Nintendo Logicness" of those old titles. Nintendo Logic becomes pathetically obvious when you're watching someone who hasn't been poisoned by it playing old games. Newer, 3D games have their own fake logic, but they resemble more closely reality. And I'm glad score-based gameplay is dead.
Also, while revisiting old Mega Drive games I discovered most of them didn't age as well as I'd expect. I can still play Sonic, and even Castle of Illusion, but most platform games are absurdly boring. Puzzle games like Columns have aged well, but that was expected (witness the Tetris DX re-release for the Game Boy Color, for example). Sports games are dull. RPGs are usually, but not always, ok. Landstalker is still playable and all, but I'd take Shenmue any day of the week.
I don't think there are many old games that can appeal newer gamers that didn't play them "back in the days". I play River Raid for the Atari 2600 every once in a while, but I doubt I'd play it if I didn't own an Atari 2600 when I was a kid. Our memories are always much better than the reality. New games suck, but so did old games.
Now, are these musings interesting enough to deserve a place in an Advogato diary? Of course not.
