If I made add. Something I was thinking about in terms of race attributes or skills is to keep it as simple as possible.
Personally Id like race choice to really be down to aesthetics. But I would like some benefit.
For instance. I know in the concept I saw what looked like a feline race. That races running speed could be enhanced.
What I mean is giving each race, one or two bonuses to a stat, if they are in the game.
