(I have never seen a map like this, please correct me if I am wrong.)

While playing CnM, I came up with the radical idea of a competition type of CnM.

Lets say there are 8 players. Each player takes turns playing the cat. Each player gets 15 minutes (or less) to kill all the mice, or the mice kill him/her, or s/he misses a few mice during that overall time. The cat gets points based on how many mice s/he kills, and loses points based on how many mice are left (maybe if the cat dies, even more point loss). But then you get seven turns at redemption. Depending on how many minerals you get as a mouse, is how many points you get at the end of each round (Divided by some other variable). Also, bases would be easier to enter, so you couldn't just hide behind a stargate the whole time.

The only problem I foresee is the length of the map. 8 players, 15 minutes each (On fastest I realize it would be less), that is 2 hours long in game length. People would probably leave. (Maybe to fix this, you could make it into 4 teams, and 6 mice and 2 cats at a time? Team with the most points wins? Then this game would be 1 hour long.)

A while ago, I made a map called "Cat N Mouse Switcheroo!!!"
It was basically a "tourny" for cat n mice pros. Each player has a pair of cats and a mouse. At game start, a random person is chosen to take their shift as cat. He / She then kills a mouse to become a mouse. If you die as mouse, you become cat. If you die as cat, it's gg. Credits would be established for each cat every "Switcheroo!".

Mostly newbs play Cat and Mouse, so I don't think it would work, as newbs get discouraged quite easily. As for Conspriacy's idea, I think that would be better.

A big problem with doing this, is the map details really.
Ex. The mineral fields. After a certain point, you will be out of minerals to mine. And no minerals = no dead cats.
Also, I find that in the rare C&M game I play, exploring the map is one of the most fun parts. If you can already see the whole thing, it's not as hard. And if players repeatedly go to the same spot, and build the same defence, the cat could notice them while taking their turn as mouse, then exploit everyone's weaknesses.

Most of the Cat and Mouse maps are ridiculously huge and boring, not to mention hugely mouse-favored.

Any map that has "hideouts" that a mouse can enter that a cat can't is inherently imbalanced, because while the mouse is sitting there with the cat's attention, the rest of the mice are mining. If the cat leaves, he'll start mining again; you can't win unless they're just bad.

I edited a 64x64 map that I find pretty balanced, but it's never used. CPU Cats and maps which are rigged for the mice are much more heavily played, unfortunately.

It it my personal belief that C&M games can't be balanced, not in the true sense of a 50% chance of victory game.
Any map that is small enough for the cat to win will probably mean a quick victory.
A map that is greater than 64x64 is too large for the cat, and results in several quickly constructed, indestructible mouse bases.

My friend made a map, you may have seen it hosted. It is similar to this map in the fact of a type of competition. It's called CnM Brothers at War. It is pretty fair, but if your team mates suck, you pretty much lose (teams are also completely randomized).

Mine would be single, and your right, unless the cat gets a quick victory, its pretty much a cat loss. That is the problem with most Cat and Mouse games, if the mice can wall up, it takes to long to tear it down, and they get a huge advantage.

It might be cool to make resources in bases run out fast on large maps, to the mice have to keep transfering bases and cant just sit in one spot.

most of the walls are easily mobile...

Common ones are CCs over units, or Medic walls, Easily movable.

No decent cat n mouse map allows medics, and I think lifted buildings should also be removed.

Or killed easily by turrets, corsairs, or scourges created by the cat. (CnM Perfect by Oo.Solar.oO and some other member, does turrets, and CnM Brothers at War does corsairs. I'm pretty sure some do scourges)

My CnM map is like that too! Cat vs Mouse LEET is my ub3r leet CnM map. I do agree that CC walls over civis is gay as hell.

So, I'm assuming you'd be pissed if a player Made a CC over a Wall of Civillians being healed by medics with a series of Photon cannons shooting from behind the wall?

lol

lol, love using that strat. Though it takes a while to get all the resources for it all. Any CnMer that doesn't suck should know the way around it though. Just unally the civ and hold position near it. ;o

PRO was the first balanced CNM out. It has medics.

Any decent "Cat" would know how to counter those. Very easilly too.
