I think you might be unfamiliar with Dungeons and Dragons. Races don't really change your gameplay, outside of a few niche cases, and in most cases, the only difference between them are the small stat boosts or bonus abilities they get. Nearly all of the variation comes from the classes and the sub-classes, of which there's going to be at least 12 classes, each with multiple sub-classes which sometimes drastically alter the way a class plays.
While level 14 doesn't sound all that high compared to video game RPG standards, in D&D there is a significant difference in the power between a level 1 character and even a level 4 or 5 character. Level 14 is higher than most tabletop campaigns ever even get to, and even then only after months and months of weekly sessions if starting at level 1.
With only act one(nearly everything except the Underdark) I was easily able to get squeeze 35 hours of playtime. That's already as much playtime as other long RPG's provide, and I'm guessing that the finished product will be well over 100 hours, which I'm happy with.
Also, you shouldn't compare the replayability of session or match-based shooters/strategy games with story-based RPG's. I doubt you played through the story of Company of Heroes 2 245 times.
