Graphics similiar to Tiberian Sun?

#1 I'm sure you can achieve the graphical equivalent to your listed games using TGE, and definitely TGEA. There is also an open source Fallout-clone engine that handles isometric game play quite well.

#2 You are almost asking two different questions.

1. As long as you have a quality artist or artists working on your team who understand how to create isometric graphics, you could potentially achieve similar results. If you use 3D models on terrain, you would want to set up the camera with orthographic projection and create your artwork with that in mind.

2. Most 3D engines can handle an orthographic projection. TGE/A with camera tweaks can do it. BeyondVirtual, Unity, Irrlicht, etc can all do it. If you can program it, Blitz3D and DarkBasic can do it as well. There are some caveats with isometrics and 2D engines, most of which comes down to artflow. If you research 2D engines and search their forums for isometrics or orthographic projection, you should be able to find whether or not the engine supports it out of the box or can be tweaked to support it without much difficulty. FIFE is the Fallout engine that Michael mentioned.

#3 Thank you for your answers. Thing is I'm not planning for a simple RTS, I'm going for an epic geo-political game, so the engine needs to be advanced. But it's way beyond my capabilities at the moment, but just checking for some directions.

Thanks!

#4 I was simply talking about rendering a game like C&C:TS. The rendering is the easy part regardless of the engine you use. But since it is the visual piece, it seems to be the biggest piece of the puzzle. Balancing your strategy and the guts of your gameplay will be a massive undertaking even if it is a "simple RTS" and regardless of the engine that you are using.

A high quality artist can get your graphics up to par. But you will require a high-quality programmer/team to get the gameplay to match.

Good luck.

#5 TGB with animated DTS's would be a good idea for something like this.

#6 I actually thought of using TGB for a TA-clone as well. I think that game had a lot of longevity for a reason and is certainly a model for a game that hasn't been used enough. Though Supreme Commander might capture that same magic. :)

#7 Yea like KKND it was so cool. C&C Generals and a few others. Sony was even going to make a pay MMO in that build style but it got canceled a few years ago.
