Which is the oldest game you're still playing today :)

Legend of Zelda Ocarina of Time and Tibia. Both helped me a lot during early years being bullied and depressed and I still love to replay them. I mean Tibia is an MMORPG but you get the idea...I'll create a sorc, level it up to 100, delete and do it again in another world. Meeting people in Tibia is totally different from other mmorpgs I've tried.
