Lhademmor, you should make it a rule that from now on everyone who posts more suggestions has to name a category to put the link in. Much easier for you that way. :)
Regarding the "MMORPG/Roleplaying" section:
These links might need to be fixed:
9 Dragons:
Alternative link Archlord:
Alternative link Kingdom of Loathing
Lord of Ultima
Myst Online: URU
... all require account creation but are still missing the footnote [1].
The following can be discriminated from MMORPGs and either put under the already existing heading "RPGs (not MMO)" or even further sorted into
J-RPGs Super Columbine Massacre RPG
RPGs (Rogue-like)
ADOM
Castle of the Winds
Dungeon Crawl Stone Soup
Gearhead
Incursion
If a Rogue-like RPGs category is created, Desktop Dungeons might fit in, too (it's not a typical rogue-like RPG but still close enough).
Also, I haven't played The Spirit Engine 1 & 2 yet, but from what I know about these games, I'd file them under non-MMO RPGs (more specifically J-RPGs) instead of Strategy.
From the category "Action / Adventure / Battle / Platform", the title Urban Dead seems to be more suited to the MMO RPG category, while Dink Smallwood would belong to the non-MMO RPGs. Bitworld might pass off for an Action RPG, although it's hard to draw the line between Action and RPG here. And the Chzo Mythos is a series of Point & Click adventures.
As for the Adventures ( Point & Click, Interactive Fiction ...):
Currently the links for Drascula and Flight of the Amazon Queen point to DotEmu and therefor account creation ([1]) is required to download them. Alternatively, one could also download them
directly from the ScummVM website though (the same applies to Beneath A Steel Sky and Lure of the Temptress).
The Silver Lining might require account creation, too, if you get the games directly from the developer's website.
