So, I was just thinking about Reincarnator in a game designerie way. Before I go there... Reincarnator is fun. Isn't Reincarnator fun! You get to keep switching!
Ok, that being said, Reincarnator has no advantageous power. Here's some points:
1) You start with no power.
2) Warrior is sad... you loose all experience when you loose instead of gaining extra. Citadel is sad too.
3) You get new powers every time you loose, which means people have to alter their strategy, but so do you. No advantage there.
4) You will likely get an alien with no flare available.
5) Your own flare is useful, "Oh gee thanks, I get to choose now," but... they really could have just made it optional to begin with and everything I've listed so far would still apply (except, you could choose not to abandon Warrior or Citadel). Actually, the Wild Flare is quite arguable MORE useful... so you really just gave another advantage to everyone else. Hopefully, its use will help you too, which it would in most cases.
6) If playing with hidden power text, you wouldn't even get to keep your new power hidden, because that only happens at the "start of the game." I would probably say that playing with Hidden Power Text where Reincarnator could keep their new power hidden would mark the first and only actual advantage.
One possible present advantage to Reincarnator is that it only changes when you loose... so, therefore, it might stand to reason that you would be more likely to ditch aliens that aren't working against the present aliens, and more likely to keep those that are. It's almost enough to soothe my soul, but I wonder well that actually operates in the chaos of the game.
Also, in a sense, Reincarnator needs no advantage, because it always has one or another. Big exception: at the beginning. So I guess, the real question here is: Is the one present possible advantage (and maybe ones I haven't thought of) enough to counteract the downsides so that you can say something besides, "Reincarnator is just playing gimped."
So, please comment, being sad with me that the funnerest alien is directly disadvantaged. Or, even better, highlight some advantages I had not thought of.
