I’ve never really paid any attention to Warframe, but just youtubed it. Kinda intrigued. How’s the co-op? One of the reasons I wanted an MMO is that a friend of mine is in the same boat looking for something new. We tried Elden Ring hearing that it was co-op, but ER’s co-op is little temporary instances of pulling another player into your world - you can’t actually progress together. The content I’ve seen so far on Warframe looks very single-player oriented, and ER has given me trust issues with things like that, lol.
RvR is realm vs realm. Sometimes it’s called WvW for World vs World. Basically it’s large scale siege style combat - you and like 50 other players from your server are attacking or defending objectives sought by another server, so you get 100+ players clashing in pure chaos. It’s a good time when it’s done right.
