Some of my current favorites:
- When I want something very easy to get into and relaxing: Orchard. Very quick setup, simple gameplay, focused on a single goal
- When I want something a bit heavier but still pretty chill: For Northwood, a solo trick-taking game (how can that even work? It does!). Recent game, inexpensive, good replayability, great value.
- When I want a nice comfy midweight euro: Newton is a great Italian-style euro that has a very smooth solo. Also online on Yucata.
- When I want something heavier but still pleasant: Fields of Arle or A Feast for Odin, some of Uwe's best. Arle is also online on Yucata, Feast is on BGA.
