You could check out "The Secret World", which offers:
roles in a party (tank, healer, dps)
various locations
one chapter is "dedicated" H.P. Lovecraft
lots of dialogues
various types of quests (even puzzles)
the game seems totally p2w free (there are various types of currency, to get rare/good gear you have to work for it yourself); bots/hackers seem nonexistent as well
the community seems helpful/friendly as well: when u enter a dungeon (these require parties due to difficulty) you'll be likely explained what to do etc.
the game is not hacknslash (cant use a controller)
it's available on steam and you pay once (but you have to pay for additional content known as "issues")
