The price 250$ is little hight compared to Unity Indie that i bought.

I have some preferences for Unity Indie :
- only one editor with panels properties for everything.
- Unity script is lot more easy than Angel scripting.
- Powerfull terrain management by the engine (web demo)

And customers don't like a lot when a 3D engine is left for dead during some months (Beyond virtual thread in 3DGS forums)!
Who can say them that gamecore 2 will not be abandonned
by authors or for months months in this year ?

Is there a demo like Unity showing if the engine have some power scene management ?

Why not putting like Unity some 30 days demo of the engine and editors also ?
All thinsg have a demo, we can't trust some engine without testing it first !
Somebody must be fool to buy something without trying a trial version
