They are much longer. But I can't imagine that GBX will not allow a player to reach the last skill, e.g. my personal fav, dual turret-spawning, without purchasing DLC for the extra skill points. Perhaps they've tweaked it so that the player can just reach one of the end-game skills with the initial pool of skill points. Perhaps they will be kind enough to tell us as this has been a concern of mine for some time.

Maybe it should be noted that I never experienced the restriction of vanilla game skill points as I purchased the game and DLCs 1 - 3 at virtually the same time.
