I did, didn't I?
Idea #2 is another RTS idea, based around the idea of giant robots.
Once upon a time, actually around 1954 (the day after Godzilla is released in Japan, actually...), one of the first of the Beasts appears on the shore of Japan. Thirty feet tall, it takes just about everything the United States has to kill it, short of nuclear weapons.
Then, sometimes weekly, sometimes daily, more Beasts of the four big types come up from the water in the Pacific Ring of Fire...and a few of them take nuclear weapons to stop. Including one that surfaces between Seattle and Portland, and requires a nuke to stop. For nearly fifteen years, the Beasts attack. Humanity learns of the nature of what they call the Alpha/Omega (A/O) field, which serves both as a shield and as a way to "break the laws of physics" so that something like the Beast can actually exist. And, desperately, they build a mechanical generator (the Beasts are some kind of bio-mechanical organism) that can replicate the A/O effect. They build a prototype giant robot-Unit One-and place it in San Francisco to hopefully fend off the first attack (okay, there's a few more in Japan and up the rest of the West Coast, we are paying attention to the San Francisco one).
They wait for an attack...and it never, never happens. For forty years, the robots stand (okay, layed out on the ground to prevent stress to their frames) as almost black sheep in the fight against the Beasts. Some mild renovations of Unit One to make sure that it can actually function over the years. It becomes a joke, something to tell on the evening news about waste and such.
One day...a detector mounted near the Cliff House goes off...and the joke has to defend San Francisco against attack.
We're using San Francisco because it's a nice battlefield to use. Lots of nice, graphical property damage. It's also got a whole bunch of "in jokes" for various robot anime...and maybe some special guest stars (if we can get the licensing rights).
The game is based around two sections-a "base building" section, where you do research, build and improve your giant robots, train pilots, create the technology you need to make it easier to deploy your giant robots (early on, they have to be hauled to the battlefield location by truck-their batteries have a lifespan measured in minutes).
The second section is a tactical battlefield section, where you face off against a Beast with your giant robots, all commanded at your "command truck" (the game interface). Lots of explosions, lots of things happening that will make anybody go "oooh, ahhh".
More details as I keep thinking of them.
