To sum it up, yes I do like this game. It has bugs and issues but I have been having fun.
Should you buy the game ?
Problery not right yet, this feels like a early access more than a complete game. I don't even know if its finishable due to being stuck on what seems like a impossable mission.
I own all the X games excluding X-Tension expansion due to it never being released here in the stores. My overall feeling of the X-Series is that it has some good elements but on a whole is quite a dry space game. Much the same way I feel about EvE Online.
X Combat was one of the biggest issues. Dog fighting just felt flat, this coupled with the feeling you were just flying a camera inside a cardboard box didn't really help. Sure the game had a boost key but all it did was get your ship up to max speed. Guns emptied there charge too fast and took too long to recharge and after a while the combat just became routine.
Rebirth changes this with a combat feel that more like Wing Commander. Boost now accelerates you faster than your max speed, allowing you to catch up to targets but in return drains your shields. Guns now over heat, shutting down but quickly will cool and the new open world system adds for more interesting backdrop to fight in.
A few times I have been hunted down by wings of enemy ships and my option is to cut my losses and run. Making a break for the closest highway ducking between stations for cover.
I was never a big empire builder in X, due to not having the time to set one up and he lies the problem I think is causing so many negative reviews for Rebirth. People expected to be able to make the same old empires but this is a new game in a brand new engine.
So to the X fan, the game is flawed, it shouldn't ever been released and everyone should demand there money back. To me, the space fan, X is a wonderful game with adventure and exploration. I expected more of the same with X-Rebirth but was pleasantly surprised to find a new game.
One thing, the voice acting is still terriable along with the writing. This isn't freelancer when it comes to story.
I wasn't disappointed with the game, in fact parts of it are fantastic. The only real game I have been disappointed with was Dragon Age 2.
