I recently played both the Sonic Adventure games for the first time. Took me a while to warm up to SA1 but I really liked it by the end. SA2 had a lot of level design I disliked, but the ambitious story and the character stuff in general (Knuckles & Rouge's weird sexual tension, Shadow in general, Eggman being a real motherfucker) makes it hard for me to dislike it as a whole. The only Sonic games I've played that came after these are Mania and Generations which were both pretty good, but it's a shame that a lot of the later 3D games in general seem to have lost what made the Adventure games interesting for me.
Now I'm playing Touhou Artificial Dream in Arcadia, a 2hu game that's heavily inspired by Shin Megami Tensei 1 and 2. I'm loving it so far, probably having more fun with it than I have with an SMT game since the PS2 era.
