For those of you who have played with the original rules and the updated (1.4/2.0 depending on where you look on the page). Do the new rules makes this a worthy game for engine building? I heard the original rules were somewhat of a luck-fest but the mechanical premise in this game make it look amazing, so I'm hoping they fixed it :-)
I don't know how deep and strategic you prefer your games. OMG is still on the lighter end but - considering its form factor - offering nice depth and replayability.
We have played both, old a new rules. We are now only playing by the new rules as they allow you more flexibility. You are not trapped as fast as in the original games if you have a hand of cards that doesn't help you much. I wouldn't say the new rules add more strategy, they just improve the overall flow of the game. And because you can make better use of your production chains in v2, you don't feel like you have missed a chance (what cold have happened in v1).
Edit: I have to add that: In my eyes OMG is a great game and worth having it.
