I havn't played many of those on your list,but would highly reccommend Immortals of Terra(nice Sci Fi adventure setting) and Nibiru(sort of Myst-like)
Some not on list that Ive enjoyed:Keepsake,Dreamfall,The Drawn series, and Dream Chronicle series(beautiful, colorful, imaginary worlds)
Highly recommend GOG to download many, many older games that have been remastered(?) to play on
WINXP or WIN7. Also you can read reviews about each game-very helpful. They have great sales too.
I too admire your bravery and effort to encourage others( including me) to look after health issues sooner. I hope your procedures and recovery are successful and that you find lots of great adventures in gameland during your hospital stay.Thoughts and prayers are with you. Keep us posted.
