opinions on new game using idtech4.5

[motorsep]

It's true, CSG level building has been abandoned for no good reason in all engines, except Source (not mentioning idTech 5 since it can't be used). However, Unity has this: http://www.protoolsforunity3d.com/probuilder/ and it's coming for UE4. Not quite CSG, but very close.

The problem with old idTech 4 (at least The Dark Mod) and its tools and Radiants, is that they don't work quite correctly on Win10 (reported on TDM forums). I don't know if the same is true for other idTech engines (Quake, Quake2, Quake3).

Quadrilateral Cowboy is a good measuring stick for this tech - the guy knows idTech 2 inside and out, was working on the game full time (at least in the beginning), doesn't have elaborate art, and yet, the game is still WIP.

By all means, use idTech 4 (sounds like reverse psychology ). Start off by making a fully animated and textured model with sounds and effects and a map, and some new game mechanics as Doom 3 mod (you can re-use it for your game). Get a feel for what it takes to get that done. If you still feel on board, good for you.

I haven't done much dev with Q2 since I got Win 10, but 10 doesn't seem to like Radiant as much as I thought it would.  It might just be security issues (IE, Radiant wants to write to it's own folder & it's currently locked), but my non-install of Radiant 2.5 doesn't even startup now.  Haven't resintalled it yet.

That probuilder tool for unity looks interesting, you said its coming to UE4 too? Is it as simple and fluid with brush editing as gtk? What did id tech 5 use?

I wouldn't say working with brushes is fluid. It's cumbersome. The benefit of CSG is in lack of need in 3D app and 3D artist. You can build levels, good looking levels, without any 3D models.

I haven't worked with Pro Builder, but it seems that you can move verts/edges/faces in 3D, which you could never do right in Radiant. So that alone makes it more fluid than Radiant.

If you have RAGE, you can download idStudio and try it. It still has CSG, but afaik RAGE levels were made almost entirely with 3D models.
