Are we finally done with this damn flame war?!? (Sorry for the harsh words, but you guys are pissing me off!)
It's fine to use some models from magitech, but I think most should be custom models. Towers are pretty easy things anyway.
I would be interested in a trying to see random enemies. For example, have lua pick a random number, then send a random number of the randomly selected foes at the player.
For example, picks a number from 1 to 5, if 1, it sends a random number from 2 to 6 of unit a, if 2, it sends a random number of unit b, and so on... I actually don't know how to pick a random number in lua, but surely it must be possible...
Each time, the counter goes up by the number of foes that was sent, until you have reached a limit. So you can have three scenarios, one which you need to reach 15 counter (defeat a total of 15 foes, but you won't know which), one with a 20 counter, and one with a 30 counter, or whatever...
