Is progressive fantasy allowed? Cause:

Final book just wrapped it up and its good.—

Sci-Fi LitRPGs:

(this is my attempt to include science fiction stories with LitRPG elements, but that focus on the science-fiction implications of VR/AI/games, not on progression)

Continue Online by Morse
Virtual Realities by Schott
Puatera Online by Chapman (the first three books have very little /r/ProgressionFantasy elements; later books are a bit more typical of the genre)

Series that can be read as complete with a midway stopping point, but have been continued:

The Gam3 by Yap (a sequel series started in August on RR, but book 3 ends a complete story)
Nova Terra by Ring (to be continued in Forgemaster )

Series that are on permanent (?) hiatus but at a stopping point that could be an ending:

Desire by Milan (not harem… Really poorly-named series! Milan calls it complete, but it’s an open ending.)
Monster Hunter NYC by Cooper (harem)

Greystone Chronicles, Shadow Sun, The Darkelf Chronicles and Mars System Reboot by Willmarth

Guild Core by Reynolds
Futuristic Dungeon Core by Grant
Below here I haven’t read yet:
A Lonely Dungeon (RR) by cathfach
Cat Core and War Core by Henegar
Blue Core by InadvisablyCompelled (adult content chapters marked; I assume so they can be skipped)

Complete web serials:

Worth the Candle by Wales
The Infinite Labyrinth by Vincent Archer
The Humble Life of a Skill Trainer by altonsleet
Mother of Learning by nobody103 is amazing, but it’s /r/progressionfantasy not LitRPG.
Below here I haven’t read yet:
Vainquer the Dragon by Void Herald
Azarinth Healer by Rhaegar (book 1 on KU, epilogue to follow still)
Everybody Loves Large Chests by Exterminatus (trigger warning: rapey demon sex, gratuitous gorey violence) (also Small Chests Are Fine Too) more NSFW than KU version?
Epilogue by Etzoli

I’m likely going to GDPR-Nuke my Reddit account, depending on how things shake out by July 1, so not sure how to share this back with /r/LitRPGs. Is it easy to link to here from Reddit? idk
