One of the greatest moments in TCoS was right when I began playing.
I had just completed the tutorial and I was at the Hawks Landing docks. Then that absolutely breathtaking Parliament exploration music started playing and I looked up at the "sky". Of course, it was solid rock with giant holes in it, and the Deadspell Storm light was coming down through them. Amazing. That moment I was completely immersed in the game and this rarely happens to me. I found the game to be so addictive and immersive that I played it for days and days, and I was continuously surprised by the art direction and the game / sound / level design.
If there's anything I hate most in MMOs is travelling. Spellborn offered no mounts, yet I never felt "tired" of walking my character on long routes. Also, with the server almost empty, I never felt alone, because I felt like TCoS was a very good game to solo. Of course, playing with a party was also cool, but I never lost any sleep over it.
Spellborn is back!
