There's a lot of SF out there which builds on this basic premise in fact, its one of the classic seven premises of SF).
I drafted out a story on these lines a few years ago, but never got round to implementing it as a plugin.
Something which I've always wanted to do, which this story would lend itself to very easily would be an EVx time-travel scenario.
Part I: you troll round the new universe, trying to keep life and soul together as you vainly pedal ineffective plague remedies on Planet W, deliver unappetising Kale from Planet W to Planet X, and avoid the pirates as you take Planet X's minerals to Planet Y, where they manufacture ineffective plague remedies, until you bump into Dr Omega, who tells you about the Tryphomorphicchronomat experiments which were rumoured to have been carried out on Planet Z. With Dr Omega, you travel to Planet Z, pursued by pirates who believe that you are trying to locate a weapon against them. From Planet Z, Dr Omega triggers the Tryphomorphicchronomat, and you blast through it in your wreck of a ship, with the intention of returning to the Nova universe (or any other earlier universe) to prevent the plague from happening. Unfortunately, three pirate vessels burst through at the same time.
Part II: you struggle in the highly organised and structured earlier universe, as you have no papers, and your ship doesn't meet the minimum safety requirements. After agonising months of trolling round that universe, you acquire enough Creditos to get yourself something legal. You then set off in to try to locate the secret lab where it was rumoured they manufactured the virus. Eventually after more fights with pirates, who have now signed up one of the secret agencies of the current world, convincing them that you are in fact trying to release a virus you find the lab, which is in the same system as the Tryphomorphicchronomat. In a pitched battle with pirates, your ship is badly damaged, and you board and take over one of the pirate ships. You blast the lab to smithereens, and then use the Tryphomorphicchronomat to return to your own time.
Part III: in your own time, you discover that it was your destruction of the lab which actually released the plague. With hardly any energy left in the Tryphomorphicthingummyjig, you blast back into the past. This time you have to destroy one of the three pirate vessels and take their place, enlisting the help of the secret government agency which you convince has to stop your earlier self from releasing the plague. You go through various adventures, finally arriving at the lab, disabling your own (earlier) self but also destroying both of the other pirate ships, to prevent your earlier self from boarding them and destroying the lab anyway. Realising that if you die earlier, you will not be around to save the day now, you scoop up your earlier self in your lifeboat, and shoot both of yourselves through the Tryphopieceofjunk. Realising you cannot co-exist with yourself for long, you eject yourself outside the Tryandgetabetteronenexttime, where the universe seems to be in much better order. Pausing only to see that you are, in fact rescued, you blast back through the Tryandstopmethistime into an uncertain future the end.
As far as I know, no-one has ever yet successfully done a proper time travel scenario, but it shouldn't be too hard with visbits and a bit of mucking around with the year (ps, you can do the year in Wetware, by changing the prefix, so that the numbers go up, even though you've travelled back in time).
(PS, the full list of classic premises is:
- Good old set in a technological future, where virtually anything can happen (Lensman, Buck Rogers in the 25th Century)
- Change one thing about the past or present, and exploit it consistently (Fatherland, Man in the High Castle)
- 'Hard core' application of real scientific discovery(s) to a story (Neuromancer)
- Evolutionary present or future (eg, introducing psionics, Babylon 5, or William Golding's 'the Inheritors', or evolution of robots in I Robot series)
- Post armageddon/decline/collapse (Twelve Monkeys, Planet of the Apes, Foundation trilogy - often based on Europe's experience of the Dark Ages)
- New species, same old problems (War of the Worlds, Babylon 5, Independence Day - often based on European colonisations 1600-1900)
- Cosmic/religious (2001, Babylon 5, Dune, later Foundation books, Star Wars)
