dito on that.
There are 2 thingies that are available for making game that do not require coding....
One is 3D Gamemaker (T3DGM) available from the DB site. They do have a demo version too. Its primative but easy to make simple games. From an absulte beginner perspective, its OK. But, it does not export code so cannot be expanded further.... The FPS thing under developement might be better as it exports code ...
Another is GameMaker

I purchased a copy of this I thought it so good. Although I mainly
use his site for images and sound effects. Also does not require code, but does export (sorta) so you can expand on it. When you learn to make DLL, you cn even add extra support ....
Also, before diving in and spending alot of money on tools, write a few levels for games you already have and see how you like the process... Some "MOD - friendly" games do not require coding to make maps or alter objectives and other things. Experiment ..
Warcraft, Starcraft, AOE, Unreal are Mod Friendly, And Sacrifice.
Homeworld and Starfleet are hard to mod. For RPG there's Dungeon Siege and Neverwinter Nights...
When you have a game idea that you can't do with a mod to an existing game, Then you are really ready for DB or DBpro.
