You can joke all you want, tundra can be a strong start in a lot of cases, even if the raw yields are less than grassland/plains. Tundra starts (as long as I get dance of the aurora) are a lot easier to pull off for me and snowball from.
The yields arent terrible compared to desert, the pantheon is rather uncontested, the tundra starts among the safest on deity due to generally a lack of neighbours (and more settling space), and the combination of work ethic, monumentality and faith buying districts with Moksha, make for a very strong early power spike.
Buffing tundra further will make it into one of the absolute best possible starts to get.
