Brainstorming a Steampunk setting

[Nique]

So I've been continuing work on my untitled game. I won't be asking questions about mechanics as much in this thread, but I am interested in hearing your thoughts on tabletop RPGs in general and specifically, suggestions for a Steampunk-esque world.

To start with, I'll sum up the mechanics to give you an idea of how it's played.

Players assign points to raw Stats which determines Ability scores. Add or subtract any relevant modifiers and roll that many D6 against either enemy rolls or difficulty levels.

Skills are a form of energy manipulation that enhance and use ability scores, in addition to other interactive features. Skills use up MP or are free to use as a part of equipped weapons/ armor (there is a cool down time for offensive skills when part of an equipped item). There are more detailed rules for this I am still working out but I am allowing for the possibility that not every class will have the exact same access to skills, and that some might not have access at all and need to use tools.

My questions for you:

In general, what kind of features do you find fun/ enjoyable in an RPG that you would recommend?

We're trying to build this in a steampunk setting - what are some good ideas or concepts to include in such a universe? How would they relate to the existing mechanics?

Also; What are some good names for the game?

Other misc. advice is welcome, as always!
