Poll: Have you ever used a game development program?

[The Paradigm]

Have you ever used a program like Unreal Editor, SDK, or the G.E.CK?
If so, what did you create?

I made a Half-Life map that was a suburb street infested by zombies. I think it was pretty cool.

P.S. I don't think Garry's Mod counts here, but I've never played it, so i could be wrong.

I like using SDK's hammer editor. Garry's Mod is more of a sandbox.

I have played around with Unity (the most powerful in my opinion). Didn't make anything though.

Interstellar Marines is made with Unity. F**king crazy quality. Btw Unity is also used to iPhone games and such.

Yes. And they all suck. Apart from this one I fiddled with back in year 3 but never could remember the name. You could make one of the bosses Mr Poo and the protagonist an apple.

I use FlashDevelop and Visual Studio primarily, but have used 3dsMax and Maya for level development, and LUA and Actionscript as well.

Though from what the OP lists, it sounds more like the title should be "What level building software have you used?" as those are primarily level development tools, though they are used as mod development tools as well.
