I'm not sure if a topic has been made on this yet, but which one do you like more? I've play Oracle of Ages and Oracle of Seasons.
My favorite is Oracle of Seasons. Don't get me wrong I love Oracle of Ages, but it was harder than Seasons, which isn't a bad thing, it's just that going through time to solve puzzles was a bit more difficult. Plus in my opinion Seasons was a more memerable game. I played Seasons a month before I played Ages and I can remember things from Seasons more than Ages. In fact I can't really remember anything from Ages. It's still a good game though I just think Seasons is better.
I much preferred Ages for not just the difficulty of puzzles but the better plot and interaction of the characters. Even the animal (wasn't it Mushi the blue panda?) was more interesting of a sidekick than the all powerful kangaroo of Seasons.
Actually, you can get any of the three animals, the kangaroo, the bear, or the red dinosaur, in both games depending on whether you found a Strange Flute or not. You can get one by buying it from the main shop in either game for 150 rupees or you can win one from the shooting range in Ages or the dance hall in Seasons. If you have neither, you get the third option (the kangaroo if I remember correctly, is the default for both games, you get the dinosaur if you win it in a minigame, and the bear if you buy it). In Seasons you will meet them in different places, but they're always lost in the woods in Ages.
It's really hard to decide which one I like better. I played Seasons first and it remains my favorite game in the series, but Ages is a close second. Mainly because when I was younger I could never get past the Goron dance thing in Ages and always had my older sister do it for me.
