It's a good point. I remember when I was nearly obsessed with The Movies game, following the boards (lionhead) quite a bit. While we didn't get very much in terms of actual gameplay structure, we did get some videos that were culled together by the devs. Moreover, some of the devs were able to post what they were working on, which was very instrumental in giving those of us following some light at the end of the tunnel.
With Spore, I didn't know obsession could be so all-consuming, but it is. But the lack of information for extended lengths of time, with no newsletter updates, no updates to the community except through official channels (corporate interviews, magazine articles, seminar attendees)--it's a little disconcerting. Especially since the delivery date has not been solidified yet--not even an assurance of "Don't worry, it's definitely coming out in 2007."
Alas, I am not a developer and this Spore team is (voluntarily) small to keep things centrified and tight. Cut out the underwater stuff, I don't honestly care; I'll get the expansion for it when it comes out. I'll just start with the land-based stuff as soon as possible, thanks.
