If you make a roleplay with alot of mechanics, you'll get people who like mechanics.

Make the roleplay to the best of your ability and infuse your passion into it, and things will be fine. You can always tone it down or up as you need to. Just make a game you would like to play and I'm sure you'll find others out there who like it too.
