Not PS4, but for PC. I've seen it for the PS4, though - looks similar to Skyrim/Oblivion. It's a beautiful game and I really love it. I was really big on Oblivion (Xbox 360 version), spent countless hours on getting all of the achievements and doing the side quests, DLC, etc. I didn't get to play Skyrim because reasons, but I actually built my current PC so that I could play ESO. I'm really bad about doing school work while playing video games on the side - it's usually only one or the other for me - so I haven't gotten to play ESO much, though I'd really like to. I think I'm going to reinstall now since I have a month off from school, lol.
Anyway - don't know if you've played it for the PC or not - but it's essentially Skyrim/Oblivion online. Super pretty game. Challenging, but not crazy difficult or anything. Not everyone is into it, but I really like it, if you couldn't tell.
Sorry, this probably didn't help hahahah.
