I'm not denying that there were some issues with The Cave, and it was far from perfect. Yet there was something about it that kept me playing, aside from the fact that I had to review it for a publication.
Now I have walked away from the game, I've had a sudden urge to go back and play through it a fourth time. It made me think - would I buy DLC if they released it? Perhaps some new characters and some new areas to explore? I definitely think I'd go back if the price was right.
