Most of the time, when you talk about old games that are good, chances are the most mentioned are either not only good but GREAT or almost exclusively from the consoles.
So this is a selection of old games in random order that aren't GREAT but they hold a nostalgic value to me, and can most definetly get the rank of "good".
THE PINK PANTHER - PASSPORT TO PERIL.
Back in the 90's, The Pink Panther was re-exposed to the world in a packet-format TV-series as was popular at the time. Typically, an episode of such a show would have a 10 minute episode with the host character (in this case, The Pink Panther) and then two 5 minute long cartoons with other characters like forexample The Blue Anteater. In Any case, the show spawned two PC adventure games for kids that would challenge them but teach them about stuff while they do it. Pink Panther - Passport to Peril taught kids (and at the time, Me as well) about different cultures and countries around the world.
The storyline is as such: There's been made a summer-camp called Chilly Wa Wa for the children of highly influential and rich people from around the world. But suddenly the children have started to act weirdly from one day to the other, Pink Panther gets assigned to travel around the world (England, Egypt, China, Bhutan, India and Australia) and find out stuff about the kids so he can try and make them normal again. All the while the kids playing the game would learn about the things children in these cultures have to deal with while growing up. There would also be songs, Awesome songs. Go check them out on Youtube. And while you're at it, check out the sequel Hocus Pocus Pink as well.
Do you like Lego? Do you like Chess? Well then what the hell do you need to know?! This game taught kids about the boardgame chess while entertaining them with short clips depending on which character defeated which. There would be differently themed Chess boards and stories, forexample: In the Cowboy storyline, a sheriff is trying to capture three robbers. So yeah. It's Chess. CHESS!
DONALD DUCK: QU@CK ATT@CK
This is one of the simplest and shortest platformers I have ever played. It's easy as boink and you can pick it up and complete it in an afternoon. Which is perfect if you have an afternoon to spend. Seriously, I know standard length for a game is 10 hours and I wouldn't have it any other way. But this game is just too much fun to pass by.
For another really good Donald Duck game check out Maui Mallard in Cold Shadow.
(EDIT: I know the picture says "Going Qu@ackers" but it was called "Qu@ck Att@ck" in Europe.)
ASTERIX: THE GALLIC WAR
It's the universe of Asterix The Gaule meets the boardgame RISK in a way. You start out with the ever-silly village that Ceasar somehow just can't conquer and then start conquering back all of Gaule from the Romans. While most of the time the conquering would be like a simple strategy game animation, other times it would switch to a platform game depending on if you're Asterix or Obelix. And other times (again) it would be a parody of the Olympic game Hammer Throw.
There, wasn't that fun? If you have other games that people really need to mention more, please name them in the comments! Maybe I can make more of these :D
