Thanks for the giveaway!
As you didn't said that it had to be a Splinterlands game, I'll talk about Tibia. I was really young when I found out the game, and it was the first time I was playing anything online. I remember fondly about being a newbie and discovering the game by myself, without internet guides or tips'n'tricks (as I didn't knew those existed back then). I won't ever feel that again, as I'm now too used on searching online for everything even before starting doing something new.
Oh man, I remember Tibia!
Back in high school, there was a group of 6-10 of us that all played a lot of that game. I'm pretty sure I'm the only one from that group who actually graduated - everybody else spent Junior & Senior year working and playing either Tibia or Diablo 2, haha!
Every now and then I think about going back to the game, but I look at the graphics and I just can't bring myself to do it :-P
