Game is AMAZING - it has most of the stuff that was in the base Battletech boardgame. But... As much as it was enough to be a board game, we grew to expect more from computer games. Maybe expansions will add more content.
Single player campaign is quite good, story line is solid while being able to simply ignore it and hunt for glory is just great. And as with most (all?) Paradox games, modding community is amazing, definitely worth modifying your game.

A lot of changes in Dharma, really worth the price. Finally India got some love, good changes to the estates and really cool government builder making your country more yours than earlier. Worth getting it asap.
