How good is Alien Egypt? To win normally, you need 30 crowns = $120. To win by Alien Egypt, you need $100 + 1 turn = $108. So Alien Egypt saves you $12, or 1.5 turns.
So, a few options:
1. Play an ordinary strategy, taking advantage of the bonuses for ruling times, and win by crowns.
2. Play your 2 cards, then sit on Alien Egypt for the rest of the game, taking money until you win.
3. Cleverly draw and play cards, earning more than $8 a turn, and winning by Alien Egypt.
4. Cleverly advance a few crowns to rule some times, earning more than $8 a turn, and winning by Alien Egypt.
I'm kind of surprised that strategy #2 is even allowed, since it doesn't seem like the kind of game DXV would want to encourage. But maybe the reason it's allowed is that it's not very strong.
