Meh. It's a great game that is definitely worth the price tag of $30 in my opinion. Tons of replayability (near infinite), emergent gameplay, and constant updates to boot. Maybe that's cause I've been a fan since the extremely early days of free BT and I've more than got my money's worth by now, but I still love BT. The visuals, the effects, the atmosphere. It's so much more immersive and Deisel-punkish than any other game, and completely unique in its genre. It's a good game that recaptures the magic of SS13.
As for not playing multiplayer, I say just do it. Very rarely have I had games ruined by griefers or toxic people. They exist but are the minority. If you're a diehard roleplay /serious player than you might have some issues because BT (like SS13) is chaotic by nature, and people like to screw around a bit, but honestly if you just laugh it over and be a good sport about some things it's still very goal-oriented and teambased gameplay, just with varying levels of competence.
But my god I just love the atmosphere. Maybe it's because I've loved the game for so long and it's so damn beautiful now, but it just nails the underwater-disaster-survival aesthetic so freaking good.
