Copypastaing a (somewhat edited) post from the last thread about newish story rec's. Feel free to discuss or provide differing opinions.
/th/: Favors Owed is promising, both for finally being a Reisen-centric story and having an original idea for the plot (as far as I know, at least, never seen a hitman-styled story on the site before). Entertaining, and will make you feel bad for Reisen even as you're trying to ruin her life. The writefag's also good at writing side H-scenes, if that interests you.
/eientei/: Shooting Star seems to be "astronaut in Gensokyo", featuring an enigmatic Yukari and decently written Eientei crew. Not much to say here.
Touhou I.N. Space is too short and slowly updating to make much of a judgement on yet, but an AU space setting could be interesting.
/forest/: MegaSen's story is the only new one here, and it's a romancing Touhous story (main targets basically being Marisa, Mystia, and Rumia). Characterizations are nice enough, even if the writing quality isn't all that special.
/border/: HY's story, Renko's Adventure. Intriguing somewhat AU plot seeming to be focusing on magicians and the corrupting effect of magic, engaging characterizations, very rapidly updating. Definitely worth a look.
/shrine/: Chronograph (not all that new, but it's the only one I'm familiar with here) stars a western magician OC with some odd connections and similarities to Sakuya, is well-written and has a lot of interesting flashbacks/discussions about magic.
/sdm/: Fae Adventure In Resonant Youthfulness is the new one here. Focused on the named fairy characters, has an interesting take on Daiyousei, as well as an amnesiac protagonist with voices in her head not reminiscent of FoM at all, no sir plus hints at a deeper plot.
/youkai/: Human Divinity, the Aki story, is nice. The prose is detailed and flowing, and there's good characterization for Shizuha, Minoriko, and the protag (an attempted human sacrifice, thanks to a villainous Kanako). Very few choices, but it doesn't seem to need them.
/underground/: Otherwise should be read by anyone who's enjoyed The Game. Fell's writing is good as always, and the protag's narration is as unique and engaging as her predecessor's. Not to mention that a Makai story is a rare treat.
The untitled Alice in Makai story, on that note, is pretty nice too. It's rather lighthearted, despite what the OP might have you think, and has PC-98 Alice starting a new life and befriending the Makai characters. Also features an amusing child Koakuma.
/others/: Theater of Youth is fun, Teruyo seems to be at least trying to subvert the high school AU curse and doing a good job so far. Large number of characters, all interestingly written.
MWiG is the other Mary and Renko story, featuring them stumbling into Gensokyo with an OC friend. Looks like it's going to be getting into Maribel's connections with Gensokyo. Not bad so far, but I'm not exactly sure why it's in /others/.
X-Communist, though it hasn't updated in a while, is funny as all hell. "Russian soldier and strike force fight aliens" is the general idea, though that doesn't do it justice.
