I've owned 1-4 for a couple years now and I just recently realized I never got Episode 5. Lately, when replaying them, I've had a couple game-crashing bugs. I don't know if I would have the same problem with Episode 5 though. Is it worth the risk?
P.S. Disregard the thread title. I posted a thread about the bug here before realizing there's a special section for problems. I couldn't figure out how to delete it so I just changed it to another question.
