I picked up X Rebirth on the recent Steam sale and have been playing it.
In short, it’s not bad. They’ve fixed most of the serious game-breaking bugs that apparently plagued the early versions. Still, they failed in their goals. They wanted to reduce some of the complexity of the previous X games to make it appeal to a wider audience, while retaining the good parts. Unfortunately, what they shipped was a stripped down game that was no easier to understand than previous games. In fact, I think the interface is more difficult overall; simple things like commanding a trade ship to buy/sell are way more clunky.
There are some things I like. Capturing is now something of a minigame; I’m liking it. You have to progressively bring down a ship’s engines, jumpdrive, weapons systems, and shields to have any hope of a successful capture, and during the process you have to complete little mini-objectives so you aren’t just waiting around doing nothing. I enjoy zipping my craft in and out of hidey-holes to keep out of line of sight when taking down a turret or shield generator. I have quite a large fleet now due to captures.
The basic missions are, overall, very slightly better than X3. There’s a lot of the same “patrol these 5 sectors” stuff, which gets repetitive but is fun from time to time when you need some quick cash. The assassination missions are a good way to find capture targets (they frequently have some good-sized capital ships). And there are station building missions, which are somewhat boring but take the cost edge off building stations (which can get very expensive).
Speaking of stations, they do have the problem (again common with previous games) of the starter economy being in terrible shape. Just building one or two stations isn’t really enough to drive the economy, though now with four of them (somewhat upgraded), I’m finally starting to make some money. This is slow going because the stations take so long to build, but I’m making progress.
Walking around stations does get old pretty quick; fortunately there’s rarely any need. It would have been a great idea if there was more variety and stuff to do, but they obviously had limits on development resources.
In short, I couldn’t recommend the same unless you liked previous installations, and if that’s the case you’ll still have some big disappointments. Nevertheless, I’m basically having fun with it and despite all the problems, it’s still better than a lot of other games out there.
