A new forum game! Woah!
To be more precise, let's assume the following things:
1. To avoid the
grandfather paradox and all variants, we assume that you, the time traveler, are anchored in time, or, say, in a parallel universe, misunderstood-String-theory style. I.e., if you go back and change something in the year you were born, you're changing the events in a parallel timeline. The events that led to your birth and the environmental stimuli that caused your personality and memories to exist occurred in the original timeline/universe and cannot be changed.
2. You can't go forward in time. A big restriction, perhaps, but time traveling into the future is an entirely different concept than modifying the past. For the purposes of this thread, you cannot travel any further forward than the exact moment you read the period at the end of this sentence.
3. You are immortal, with some conditions. You do not age in any perceivable way, but you can still accumulate memories and such. If something happens to you that should be fatal aside from disease or the aging process, all your changes to the past are undone and you revert to the original timeline (see 1). Players can commit suicide to "start over".
4. You can assume any shape, human or otherwise, to blend in to your time.
5. Before trying to stop World War II/The Holocaust, think to yourself whether killing Hitler would have solved the underlying political problems leading to said events. If you still think the answer is yes, we'll all look down on you for being incredibly cliche.
6. Finally, players are heartily encouraged to manipulate the past to their own selfish ends.
Lay out your entire plan, and I will attempt to break it. Because of the death part of rule 3, this cycle could theoretically continue forever.
Let's do this thang.
