Wow one of my favorite genres if not my favorite...
So instead of going all out I am just going to let you do some research LOTS of good games exist.
First and foremost you need to try Quest for Glory Series, as it’s a combination of adventure and RPG. Looks like you like RPG by your "Currently playing" list.
Then I would hit up
www.AGDINTERACTIVE.com who has revived if you will the first two Kings Quest games... With speech full music and 256 colors instead of 16... Best part is they are FREE!
AGD is currently remaking Quest for Glory 2 so the whole quest for glory series will be in 256 color (as sierra remade the first)
That is a must hit up agd or as it used to be called Tierra
Also kings quest 9 is in development but it’s a while off yet try kq9.org I believe.
Then try
www.Justadventure.com and look around its full of great games and links to other awesome sights with plenty of reviews. Actually I think their review was on Runaways cover or a snippet was at least. Very credible sight.
Then don’t forget that multiple games are remade and sequels of high quality are also abound. Like Maniac Mansions sequel. etc. All for free on the homebrew sites. I can’t remember the name right now but its mentioned on just adventure and ADGinteractive.
One of the games that grabbed me the most was Sanitarium. It can sometimes be found in jewel case form at Walmart for $10 new or ebay has em.
I personally have not liked many Dreamcatcher games as they stray from the old style point n click adventures.
Also don’t forget Lucas Arts and Sierra, as anything from them was gold in their days.
Maybe even try Syberia. But start with the older games, as they are a little quicker to beat than the newer ones... Runaway 2 is coming FYI...
* looks like I need to add some commas.... Oh well.
