Greenlight is a mess right now, no doubt about it. Went through twice so far, some games popping up 3 times or more, others not at all....
Anyway, I've gathered a few that look interesting. I'll start with the ones you might be familiar with from kickstarter campaigns (finished and still running ones), so backers could support them.
Expeditions: Conquistador - tactical strategy / RPG
Project Giana - platformer with a twist
Malevolence: The Sword of Ahkranox - first person dungeon crawler
Kinetic Void - space sim
Chuck's Challenge 3D - puzzler
Armada Online - multiplayer space action
Games you probably heard of before or at least should have.
Afterfall InSanity Extended Edition - survival horror
Kenshi - free-roaming squad based RPG
The Age of Decadence - isometric, turn-based RPG
Project Zomboid - Zombie sandbox game
Towns - citybuilding / management game
Underrail - isometric RPG
Miner Wars 2081 - space action / sim RPG
Transport Giant - classic sim strategy game
Xenus 2: White Gold - FPS
Unepic - platformer RPG
those I discovered by accident
Dawn of Fantasy - multiplayer strategy
Dangerous - space combat RPG
Folk Tale - real-time comedy-adventure-strategy game
Call of Cthulhu: The Wasted Land - turn-based RPG
No More Room in Hell - Half-Life 2 Zombification mod
Guerrilla Bob - cartoony twin-stick shooter
Gnoblins - 3D roguelike. Had me with "construct your own dungeon with the help of the gnoblins"
Swords and Sorcery - Underworld - classic old school dungeon crawler
Last but not least -
- I'm sure you get it here from [url=http://www.gog.com/en/gamecard/inquisitor]gog.com, but I'd guess voting them up on Steam wouldn't hurt them.
