It's not technically old, but rather indie web-related, I guess! If this is the wrong area feel free to move my topic, though (o^▽^o)
I found this cute little browser game called Riverton, where you raise farm animals, race horses, etc. It kinda reminds me a little bit of Neopets! (* ^ ω ^)

I've been playing it and having a nice time. It's very nostalgic-feeling. I'm always looking for actual fun cute stuff to do on the web, so it was nice to find this!

Ooh, seems fun!! I'll have to check it out! I do enjoy a cute little game!
