📣 Thread Warning

This thread is about TLOU 2 sales... The legs of other Sony games may relevant to the conversation. Comparing the legs of Sony games to Nintendo games is, as far as I can tell from reading the posts here, not relevant to the conversation, and has completely derailed the topic. 

Feel free to make another topic to discuss that particular issue, but keep this topic focused on TLOU 2 sales.
