DOS attracted lots of casual players while POE was marketed towards old school RPG players.
What the fuck are you talking about?
Project Eternity crowdfunding started 2012 with the promise of a new game that's reminiscent of old Infinity Engine titles.
You cannot easily get someone who has never played an infinity engine game to play POE with its pre-rendered backgrounds and "complex" RTWP. Original Sin 1+2 are games that are a lot easier to get into for someone who has no experience with RPGs.
