Notes

Single card size (63.5x88 poker). 208 project + 12 corporation = 220 gameplay cards; +8 overview cards. Ryker's kit ships 233 sleeves to cover all 228 with spares. Sleeving is popular here because the base cards are notoriously thin/prone to wear.

The same sleeves fit these games

Sleeves come in packs of 100 and Terraforming Mars will not use a whole pack, so it is worth knowing what else the spares cover.

Not every game is standard: Faraway (70 × 70 mm and 44 × 68 mm) and Harmonies (70 × 120 mm) need their own size.
