I think I will just stick with a model as the sun. If someone can produce a working, good-lucking, emitter that doesnt lag...call me :) (well..PM me)
As for the realism issue that many seem to be worried/glad/intruiged about. The answer is in between. I want it to be playable and am constrained by TGE restrictions. I am however doing what I can too maintain some level of realism. The planets (as I have said many times) are very, very far away and a custom vehicle will likely be needed. The planets are also huge.
Features I think would be kickass and might work....
>Rotating cloud layers (to bring the planets alive)
>Proper sun effect (any one got an emitter for sale?)
>Custom interplanetary transport (lots of speed, capacity and comfort)
>Oxygen system complete with airtanks, airzones and death! (Nice challenge for the coders out there)
>Atmospheric Conditioning system (adds to oxgen system, means that things like temp and pressure must be kept stable)
Features you definetly won't see...
>moving/rotating planets (as if)
>A map with planets spaced billions/trillions of miles apart
>Easter eggs (Ok...maybe just a few :) )
>DM friendly (I HATE DMs. Build you own! >:( )
Ok....thats my 'wish list' finished.
