I wouldn't call Cortex Command garbage, just near unplayable. The problems with the Devs of CC is that they don't even have the basics down. You know, things like walking straight without falling over. They are so tunnel visioned by the physics system that they don't realise why certain things are intentionally abstracted out (Like walking) so you don't have to program a physics system just for the legs just so it can interact with the ground which is another phyiscs system altogeather.
All that just so the player can walk. The AI then has to deal with this too. Even something a simple as a rocket which NASA could land without too much grief was done with a computer less powerful than a wrist watch is made endlessly complex by their own systems.
I admire the devs for shooting so high, but their aim is vertical, all that stuff they launch is going to come straight back down on top of them.
Cortex Command is a fun toy, but I doubt it will ever be a game.
