[GD-Design] A few questions

[Death H. <dea...@ga...>]

Hello all!

    I have been waiting for such a game list for a long time now. I hope =
the following questions belong here.

1. When designing games, engine design is very important. So I was =
wondering what is your method of choice for culling? BSP? Portals? =
Octrees? Something else?=20

2. I am currently trying many different techniques, and I always need =
some sampla level data. Can you recommend some (preferably free) level =
editors with ability to export to a custom format, or at least with a =
good documentation about the available format?

Thank you.
