Geneforge/YMMV

• And It Worked: In the first Geneforge joining Trajkov gets you arguably one of the best endings. There is a terrible war and you and Trajkov Take Over the World, but Trajkov grants the Serviles human rights and ends many of the Shapers' more evil practices.
• Game Breaker: In some games, the Vlish. They are cheap to create and cause both slow and poison status effects, making a sufficiently-leveled pack of them unbeatable even on higher difficulty levels.
• Goddamn Bats: Enemy Vlish. They swarm and cause a variety of negative status effects.
  • Podlings in V have area-effect attacks that inflict negative status effects. And since different varieties inflict different effects, it can get very annoying very quickly.
