As many here, you're really boring playing on every words. I add a "I think", so you can just stop answering to say nothing...
To be fair, people weren't really playing Baldur's Gate before they got re-released. Well I was, but modding the games to run like EE's was a pain in the ass. BGTUTU for example, it took so much tinkering that your average gamer had no interest in. So I guess whether current RPG's will be played in 20 years or not depends on if they'll be kept alive by updating and possibly re-releasing them.
And you're again talking about you as "poeple". Lot's of people still played BG before EE exists... And lots of people still plays the original games even if the EE exists... Maybe you don't, but that's not why it isn't true.
On the other hand I can absolutely agree than some players re-discover (or discover) the game with EE.
