At this point, the plan is to let players make gameplay videos, for several reasons.
1) Saves us time. We're a small team and right now the main concerns are to keep improving the game features, ironing out bugs and get you guys playing.
2) It probably sounds strange, but we don't want or need more hype. We're building a nice small community right now and that's exactly what we want for the Prelude.
3) As mentioned above, a developer made video might not reflect real gameplay. I think it's just inevitable if I turn some artists loose on making game videos they will make them as nice as possible and we do have flexible camera views to do so. Also, we are more familiar with the game.
Player made videos are good in my opinion as they will reflect more what the first time player sees.
once we get the SpeedTree upgrade fully integrated we plan to release more screenshots, let people release videos etc.
A problem with this SpeedTree upgrade is that it required us to upgrade all tree models. Rather than use trees from the SpeedTree libraries, we've had to create our own trees for the most part (We're using only trees that exist in the Tahoe Basin).
We've been temporarily testing with SpeedTree library trees, but they are way off, and we're not going to release any screenshots with the temporary trees in.
If you want to wait to pre-order, that's no problem. We prefer to start off small and add players over time, rather than start off big.
