already have a large investment of hours in free games such as Fortnite

If you like f2p stuff like PoE then Warframe is also really good

Play outlast. It is the best horror game.

playable as offline and single player :
The Forest (have a perfect story-line and good experience) - the flame in the flood - middle earth series

or with a team
