Just trying to start a conversation and see what people are interested in. Nothing special about the categories - add anything you want to talk about.
Favorites limited to ones I've played.
Overall: Fallen by Perplexing Ruins. Love the setting, atmosphere and mechanics. I have some quibbles about healing in the default rules but want the Fear mechanic in everything. It's great for both groups and solo.
Combat: Lancer by Massif Pres
Solo: Broken Shores by BlackOath Entertainment. I haven't managed to keep a PC alive for longer than an in-game week, but it's awesome. Runner-up is Riftbreakers, also by BlackOath. Much less deadly and more heroic. Also the best run-a-group-solo that I've seen.
Magic system: Path of the Aram Thyr by BlackOath, again. Another solo, and I'm not a fan of the game-play loop, as written, but that is easily fixed by making your own narrative/PC goals. And the magic system is so cool.
Supplement: Lots here, but from what I've used in games is a tie between Into the Cess & Citadel and Into the Wyrd and Wild, both by Feral Indie.
I've got a large TBR/TBP pile, so a couple of things I'm very excited about: Across a Thousand Dead Worlds (BlackOath), Salvage Union (Leyline) and Goblinville (Narrative Dynamics). The current top of the TBP is Pirate Borg, Runecairn and WWN.
I personally really love the Fate system - it's much more hackable than other systems, so if a part doesn't work for you, you can usually tweak/remove it, and it sells "system toolkits" which essentially are homebrew guides.
Overall, I find most heavy systems tend to put a crazy amount of focus on combat, which skews stories into pigeon-holing combat whenever possible. Most players I run for tend to view combat as a last-resort, so it's hard to find heavy systems that match their playstyle.
