Zero-K is a great game, my favorite RTS game I have played, and I have played quite a few. I have been thinking a lot about how to make it better, and I came up with something, something that would probably add a whole extra level of strategy to the game.
Formations.
I was thinking about my units, thinking that it would be way more useful if my recluse's were in the back, and my other guys in front. I could spend some time rearranging them, but it is just time consuming, and it gives my enemy more time to attack. But if you had a button that rearranged your units so that your tough riot guys are in the front (like redbacks), your venoms are right behind them so that they don't take all of the damage, but can jump out and stun the enemy when it nears, and the are hermits behind them, with the recluses at the back, it would make a lot more sense, look a lot cooler, and be way more strategic.
I was also thinking that a couple formation buttons (one for a wedge, one for a circle (it would be even cooler if it told the units on the outside to rotate around so they all take equal damage), or just a strait line formation) would not suit everyone in every situation, So, what if you made a certain page in your home page that allowed you to customize your formation buttons, sort of like the commander customization thing. If you did this, then those that didn't know how to customize would still get some basic formation commands that would work, but if someone was picky about it, then they could go and just customize theirs to be what they wanted it to be.
I realize that this is probably extremely hard to implement, considering things like having them rearrange themselves while at the same time moving to a specified point like you told them to. But I think that if this was done, it would be more than worth it. Not only would it make strategies more effective, it would make the game way cooler, and it would add an entire new level of strategy to the game, wedges, rotating circles, boxes, line formations, and more!
