Rts

#1 Well, there's nothing in real-time strategy that ties you to a particular rendering technology, so you could simply do your entire RTS game in 2D (they all used to be 2D back in the days) and avoid 3D content creation altogether. I'd recommend taking a look at Torque Game Builder then, in case you are not already using it.

If, however, you want to have 2D sprites of your units and buildings in a 3D game, then you are certainly in for a good deal of ugliness. It is possible by means of billboards but definitely more of a hassle than building things in 3D.

As for easy to use 3D software, one good approach is to start models in SketchUp and then refine them in some more elaborate 3D package.

#2 As for 3d solutions (Rene pretty much covered 2d) have you seen the program milkshape? It's about $20 and it fairly easy to use.

#3 To be honest Paul, using 3D software (or 2D software) involves a commitment to the learning curve and there are no short cuts. Getting past it so you can focus on art creation will take time - 3D is arguably the hardest. I would estimate if you used it frequently, you would start feeling comfortable with it in about 3 months (maybe longer - maybe shorter, depends on your aptitude and commitment). You just have to stick with it. Most people give up far to early in the learning curve. It comes down to you.

As a note: Easy to Use software (As well as the best software to use) is a subjective assessment. Your own experience with the tools will eventually decide that but you first have to get stuck in and stick with it.

If you have an artistic background, 2D sounds like a good approach and there are some terrific examples of 2D rts games out there: Sudden Strike, Age of Empires and Warcraft for a start. Check out the TGB Adventure kit as well. There are other resources on the forums and blogs.

As Rene says above, the Torque Game Builder might suit you better than TGE.

Good luck :)

Edit: spelling and apology for the lecture :D

#4 I second the 2D+TGB Adventure Kit recommendation. The terrain textures (animated water, too!) alone make them worth the purchase. They're just so versatile - and you DO plan on having water units, right? ;)

2D is always a great learning experience. Get the mechanics working first, and worry about 3D with terrain and all the tricks you could do then after you drum up some interest for a sequel/upgrade.
