If you need something to play this weekend you might want to check out The Elder Scrolls Online: Tamriel Unlimited. It’s an MMO that’s been out for a few years and boasts some grand scale open world PvP as well as some good PvE. The game is currently free to play until December 7th. I played it for a while a little over a year ago and although it was fun it wasn’t what I was looking for at the time. I will say the open world PvP map is absolutely huge and the fighting I did do was quite fun. I think the key to enjoying the PvP is joining a guild and following coordinated groups. Capture points change hands and the battle moves around the map so quickly if you’re playing solo you can easily miss the action.
Did I mention it has fishing?
