Pick any game on the Steam forum and read what's there. It's mostly people complaining. So you can't make any judgement about BoS by the fact that people complain about it on Steam.
What about Steam user reviews?
Go figure the highest score there is for a game that's extinct. Then next is another out of date sim. Rise of Flight which is the best of all of em gets the lowest score. BoS is higher than RoF. Yeah that all sounds relevant. (Not)
Oh and it's a good thing of the like 260,000 people who own RoF 334 bothered to review it on Steam. That's a good sample size...? So user reviews are pretty much not relevant.
