original_response: Playstation 4 is my favorite place to play games.  It's the 8th generation of consoles.  I can't wait until the 9th generation!  Do you have any consoles?
history: I was surprised to find I loved The Walking Dead. Not my style, usually. Do you watch? No I don't actually but did you know its available on stuff like the Xbox One, PlayStation 4 and Kindle Fire? No but I think we're talking about two different things. Anyway, I've been thinking about playing Plants vs. Zombies, have you any info about it? Yes, it's about a homeowner using various plants to stop a zombie army from entering their home. Cool, is the game available on mobile, specifically the iOS system? Yes, there's an version for that in 2010 and a iPad HD version as well. Okay, I'll definitely download it when I get back. You know, I've also been thinking of getting a PS4 for the Walking Dead game, can you give me some info on the PS4?
knowledge: PlayStation 4 (PS4) is a line of eighth-generation home video game consoles developed by Sony Interactive Entertainment.
