Being a KQ fan since 1995, and waiting for almost a decade for another KQ game to come out after MOE, I have to say that when TSL is released, besides being very very excited to play it and really happy, I'm also going to feel a bit awkward, but in a good way.
It's like...Wow...I'm actually going to be exploring the Green Isles again, you know? And this time in 3D! And I'm actually going to get to meet Shadrack, and know about the BCS..
For me, it'll be like coming inside a house that you lived in and have memories of from long ago, but haven't been inside for many years. Or like meeting an old friend from a time long past. Maybe I'm just nuts, but that's how I feel.
And I also feel that it's an exciting time to be a King's Quest, or Sierra fan in general, and I hope that other fan projects (Such as the SQ7 project and others) have as much success as POS has had that way new generations can enjoy the Classic Sierra games and the old school fans can relive them again!
