I was recently playing Vessel since it came in the instant collection on PS+. I even wrote a review for it on the PS3.

Is the steam version as buggy as the PS3 version or were all of the bugs just from downgrading it to PS3? If the bugs aren't as bad I'd love to pick it up on steam for when I want to revisit it. It's fun but...yeah.

It's a great concept. If you have PS+ it's free so you might as well give it a shot. They've been doing patches so maybe they'll fix more of it.

I've heard mixed things about the PC version in regards to bugs. Some say is ran perfect, others say it had a bit of them, but nothing as bad as the PS3.

You could have just gotten unlucky. I remember playing Fallout: New Vegas a long time ago and everyone was complaining about the horrible amount of bugs and such for every version of the game but mine ran perfectly fine for the 110 hours I played it. Sometimes you just get lucky or unlucky.
