I have recently started playing our games with a starting score of 3 (which automatically goes up to 5 in the first turn).
An egg appears in the first round for bidding.
Using the normal rules the first player will probably bid 2 to get it - but no one can take it now and that player has an advantage from then on. And at a cheap price.
With more points at stake at the start, players can bid more heavily in the first round. The early rounds are important to getting a good head start or getting good mutations, as they might never appear later in the game.
The game begins with everyone at 10 points (going to 12 in the first "Phase V").
