Moonbase Defense

It was too easy, I had to hit C to try get some worthy opponents, but no. Placing of the cannons could've been strategic if it was better balanced. Selection of nodes was not optimal, I had to walk thorough a lot of nodes before I came to the one I wanted. With some more time I think this game will be fun!

Really cool idea ... looks great in 3D ... +tech points. Fairly innovative take on this style of strategy. Good use of theme ... there were indeed towers in this game. I think with polish, and some extensions, this could become a really fun two-player RTS ... eg, apart from the stuff in your readme and obvious bugs ... I'd like to see visual cues to make tower selection and aiming a little easier, some more scary creatures. Not sure if creatures can destroy towers/tubes yet, but that would make sense too. In two player mode, each player could build a separate base which included "creature spawning towers" ... Blizzard better watch out, their Starcraft 2 launch could be overshadowed :)
My game eventually ended when the gun turrets grew and grew to engulf the base. I think there is a bug :) (I'm sure you knew that already ). No sound ?

With a bit more time this could be quite good. As it is it misses on a view parts:
The selecting of the nodes is unwieldy. The jumping about with the camera makes me loose the overview. There's also a view bugs with the cannon's. They started to shoot in the air, albeit still hitting the bugs.

More, different enemies :)

I would agree that this has a lot of potential, but doesn't work as is. The interface is an absolute nightmare, and there are a lot more bugs than the ones that are supposed to be attacking. But it's really an impressive construction. I actually have Moonbase Commander, it's a cool game.

Lots of potential, however I have to say it was too easy. Also, there was no incentive to building nodes since you can have an infinite number of towers on the first one. Really impressive for 48 hours though :)

A more mouse-based control system was sorely needed and some crazy graphical bug with the gun towers made it unplayable in the end, sadly. The graphics were cool however.

Controls aren't great, but 3D is always fun. Huge amount of potential.

Horrible controls. Otherwise mostly tower defense with a somewhat non-restricting restriction.

Graphics would have benefitted a lot from better/more high res ground texture.

Loads of potential here for fun. Controls are a bit unintuitive unfortunately, and the camera doesn't help.

Not a challenging game, and I managed to get a horrible graphics glitch :D One of my turrets became so big they occluded the screen.

Otherwise, a pretty interesting game, and it's nice to see 3D games. :)

Weird graphical bugs on the towers. They seem to start spinning and scaling randomly with quite humorous results.

Awesome tower defense idea.
Very nice tower graphics - unfortunately, after a short while I couldn't see anything thanks to random texture planes leaning this way and that and covering my view.

I think the game might've been too easy, but I was actually too distracted by the graphics bugs to tell. It got unplayable after a while :/

I would've liked to try those two others concept of yours as well, they both sounded awesome. Especially the one in the all-new auction/action genre. :)

Nice but the controls are very unintuitive.
