Suicide card
A fancy way to surrender. It will also say "Player has committed suicide" instead of "Player has surrendered" in the order list.
Edit: A player whose income or stack count is less than half of the opponent's will receive a suicide card every turn he fails to surrender.
Too funny!
But I suspect the people targeted by this (don't surrender types) would still be averse to suicide
Maybe it could be a "glitch" card that ends the game with:
"A Warzone glitch has occurred, resulting in elimination of player X to no fault of their own"
This occurs iff they opt into it themselves by playing the Glitch card. Every turn they don't while they still have <50% of opponent's resources, it nags more and more:
- after 3 turns, "oh my you're quite behind, you do realize this isn't going to end well for you?"
- after 6 turns, "ok, you're just being stubborn now, do you need help finding the Glitch card or the Surrender button?"
- after 10 turns, "this is your last warning and your last chance to save face by ending the game of your own volition"
- after 13 turns, player is eliminated with message "player X has committed suicide"
