See what they did with the name? SEE WHAT THEY DID THERE?!
NEStalgia takes the classic 8-bit RPG and makes it a online role-playing experience. This comes from Silk Games. Create parties and go on an adventure in a blocky world full of random encounters and jerky three-frame walking animations. There's little towns, inns, caves, dungeons, bosses and even that wooshy sound effect when you're encountered out of nowhere. Sounds like a retro overload to me.
The game is free to download and play and the servers are always up. Give it a try. Let us know what you think of it.
