old 3E GURPS Time Travel had two awesome takes on how to make timetravel worthwhile. One was that you were fighting against another 'alternate present' that had a given probability of emerging, vs. yours. If either 'alternate present' got too likely, they would push out the other from being able to travel into the shared past. Thus, you were FROM timeline B-sub-1, you were contending with other time travelers from Timeline B-sub-2, and you had a shared past of timeline A. There was a 'blocking window' of the characters lifespan or so (the year is 2030, can't travel to anything more recent than 1970. There was also a lot, LOT of consideration of the 'observer effect,' in that if you read it in a history book, it could be wrong, or happened differently, so don't look at something if you care to change it. Then it's locked in. They also handled the idea that if the timeline changed, so did your memory... but there were certain 'psionic/empowered' individuals that could remember all timelines that changed under them and know when 'something had changed.' In other words, you can't just throw time travel into your game and expect it to work. More or less you need to think out a whole time travel setting and mechanics for it.
That seems like a very interesting and intricate system for time travel, and I especially like the idea of memories changing or becoming fuzzy as events change, kind of like in Looper.

You can only influence your original timeline if you have a discombobulation device. They are hard to come by.
Soooo... eBay?
