I think it's worse than the 2D version, as I believe a win may be assured for one player.

Yeah, a win is guaranteed forr the person who goes first.  As far as I can tell (no real mathematical proof for this) if you are playing on a ND board, you need a grid with N+1 squares on each side ie 3x3 for 2D, 4x4x4 for 3-d (trying to get 4 in a row).  However, I think that this will always leads to a draw.  Perhaps ith a time limit for play, the larger N will become tough, because you can't keep trackof it all in your head.

Hmm, I'm not sure your hypothesis generalizes to higher dimensions.  I agree that 3x3x3 is always a win for player 1, but I played a lot of 4x4x4x4 back in school and if there's a winning strategy for either player it's certainly not obvious...

The hypothesis doesn't even get into 3D - 4*4*4 is a first player win (according to Wikipedia)
 
It's obvious that such games can never be a second player win - the first player's extra move can never be a liability.
