Before i played Warframe i have played multiplayer shooter like: Cod, Battlefield also enjoy crasy scifi stuff like Borderland
So Waframe is a combination of all those awesome things:
I also love playing Flight fighting like BF Airdog fights
This lead also to likeing Archwing mechanics its remind me to Zone of the Enders series
The grind of the game is bad but waht ever no game is perfect.
Often i left Warframe for 1 month to have some variaties & dont get burnt out i enjoy also roleplaygames or adventure like Assasins Creed or enjoying Darksouls series
Not only i enjoyed Single or Coop games i also like the PvP aspect.
This lead to likeing Pvp in Warframe
