So, as I mentioned in the Costume Request thread, I recently made a character in the CoH private servers that can be explained as a girl in a mech. This is a pretty cool concept you don't see played with very often in the superhero genre, despite power armor being fairly common, which is part of why I decided to go with it. Unfortunately, this had a side-effect. Despite there being sounds for footsteps from robots (you can hear them when you fight robotic enemies, or a mastermind summons robots) you have no way to choose them for your own character. I was stuck with hearing my character grunt like a man every time she jumped, and footsteps came across like she was just a big guy wearing boots.
This is, I think, something that could be played with as an additional customization option. A library of sound packages would be really cool to have on hand - for example, the default could be standard male and female sound packages. Then you could include "monstrous male", "monstrous female", and "Robotic" as options. I doubt these would be difficult to design in the first place, it's just a matter of having the systems in place to actually have them available for players to choose.
Even if the sound effects were only footsteps, "you got hit" sound effects (as bullets striking you is gonna sound different if you're in tights versus a giant metal suit), and vocals (grunting as you jump or get hit, a laugh sound effect), this'd be a massive improvement over anything else on the market. When I mentioned this to my boyfriend, he pointed out that he paid for announcer packs in Starcraft 2 specifically because customizing the audio you have while gaming is an important part of the play experience, and in a game with character customization as important to the core design as City of Titans, these sorts of sound packages make sense as an option players can choose, and would likely sell fairly well as part of the monetization process.
An infinite number of tries doesn't mean that any one of those tries will succeed. I could flip an infinite number of pennies an infinite number of times and, barring genuine randomness, they will never come up "Waffles".
