Engine for 2.5D spaceflyer in OpenGL?

Question

Programming

There is an idea for a game - a space flying game on OpenGL.
The main mode is flight inside the star system, a view from above (from different distances), movement in one plane - by “scrolling” the outside world, but I want to make objects three-dimensional, at least planets and stars.
In the same mode, you need a HUD (radar, status indicators, etc.)
You also need a simple GUI - menus and pop-up windows during the game.
Shaders are desirable - for a beautiful implementation of a wormhole, "star gate", etc.
I would like a ready-made engine that will save time on low-level programming of everything and everyone, but which will not have to be heavily recut for this task.
Suggestions for libraries are also welcome, which will make it easier to build the engine yourself.
The game also assumes a scripting engine for part of the game logic, so if the graphics engine, library or their basis helps in any way, it will be a plus. A scripting language has not yet been chosen, but it is desirable that simple things be done simply in it.
Language - C / C ++ (let's say C #)
Platform - only Windows for now (if the engine allows cross, this is a plus)
License restriction - free, GPL / BSD / MIT / etc - so that the development result can be at least posted for free.
So far, I'm looking towards the SFML library and the Ogre3D engine.

Answer 1

DGLE2
is under development, but already more than usable

Answer 2

Ogre or irrlicht.

Answer 3

I tried to develop on this one: www.opentk.com/ .

Answer 4

IMHO either Ogre or Unity.

Answer 5

If you have a top view and movement in the same plane, then it is better to look for an engine for strategies.

Answer 6

Unity3d Indie Edition. Only with the GUI it will be necessary to try to optimize, the GUI is redrawn there (shoots the method for drawing) more often than once per frame.

Answer 7

Offtopic: are you by any chance related to the game "Empire"? :)
