But, again, RTWP is like a whole different game system mechanic and style of gameplay. To implement that would be a hefty change and lots of time, coding, and bloat the size of an already huge game.
I get maybe having it be a DLC maybe it some point down the line, but I really hope they don't spend time and money and such on it right now. Complete the game with TB first. Give us our races and such. Then maybe do RTWP as a DLC. Maybe.
