Personally I don’t think these people should be having private conversations with minors at all. It’s fucking weird and stupid and just leaves them open to this kind of allegations.
It is grindy but for the most part not so grindy that it gets boring unless RNG really fucks you. You can accomplish most individual goals (ie. Farming parts for a particular gun or frame) within a few hours. Also you need pay to win currency for some things but its easy to get items you can sell to other players for that so really you don’t need to spend money on the game at all. It’s a lot of fun. I probably have more time in Warframe than just about anything else. Except maybe Wow.
One time back in Halo 3 in a FFA game I killed everyone else on the map twice before I died, and that death was from a grenade I threw to finish someone off when I ran out of ammo and had to melee him. I have never felt that powerful before or since.
I have like 1000 hours in Warframe and only spent like 20$ on it. Even that wasn’t really necessarily. You can farm shit and easily make enough of the in game money for what you need selling it to other players.
