No, it's not bad luck. It's just the way the industry is and has been since the mid 2000s.
As I pointed out in an earlier post, if it was just Obsidian how do you explain the independent studio genocide that happened during the 7th gen? I mean who's left, really? Platinum, Avalanche, Obsidian, Techland, Insomniac, and Remedy are really the only guys I can think of who still make these types of games while remaining independent, and PG, Remedy, and Obsidian are struggling atm. This vs the hundreds of like studios that were around leading up to the 7th gen.
Obsidian just gets more attention both because they make great games that people love and they're miraculously still standing around to tell the tales at all. The sad thing is that there are hundreds of these stories from thousands of other devs that you've never heard about because they weren't Obsidian.
