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.
Apocalypse World 2nd Ed. has given me the most delight in the fewest sessions of any TTRPG. It takes a group willing to follow the rules though. If you try to play it the way you play D&D it won't work so keep that in mind.
With Apocalypse World, I haven't had a single bad session. They've all been interesting and hilarious. On the other hand, I've had all sorts of awful experiences with many other TTRPGs...
I can't wait for a new edition to come out!
