Yeah, this might not work so well due to speed runners (don't be offended, I think what you guys do is awesome), so maybe a no speed running rule, or we'll play a map the speed runners haven't played, so they can't use any cheap tactics, although they'll still probably beat us.
This is just me, but I hate having to make a cobble generator to get stone. I also hate "shaky starts" in a CTM map, especially if they last for a very long time. But I've also got a pretty fast playstyle (mostly,) so I like to get through areas quickly and efficiently, and if a necessary cobble generator is standing in my way, I'm much more likely to give up because of the monotony. At the end of the day, it's down to personal taste. A map designed by someone who likes taking areas slow and methodical has a higher likelyhood of not meshing with someone who like to speed through maps, or even someone who likes to play at a moderately quick pace.
The Skeletal archers line up in their ranks. All clad in dark leather armor, they aim their bows into the dark, twisted cavern of war. Finally, they shoot. The deadly fire arrows flew at deadly speeds, hitting the enemy's forces with a destructive blow, causing explosions upon explosions, creating a massive crater of fire and burning the shiny metal remains of the fallen Golems.
The Gate to the Lands of Desire has been opened. This wicked region of ferocious beings is at chaos. Will you bring peace to this land?
