[Different Starting Locations for Different Races]

I find different beginnings to be a very nice inducement to replays, because they pay off the decision to replay right away. They can be race-based, or they can be class-based--like if players always start in the same city, but different parts of it--or they can even be some sort of personal "background" story independent of race and class.

[(im)possibility of a toolkit?]

I'd love to see a toolkit. Business-wise, toolkits have significantly extended the sales life of many old-school RPGs, so there is clearly a lot of overlap in interest and customer base. Plus, I would argue that lack of multiplayer increases the appeal of a toolkit to both a business and players. Multiplayer allows the same content to be experienced anew multiple times; without it, a toolkit to allow players to experience new content becomes a key component to maintaining interest in a series in-between official installments.
