Visitor event in a nutshell

So, yeah, the entire Alien event was just a giant self contained paradox. Kinda lame.

Not even. Even if you use time travel logic none of it makes any sense at all.
1. Visitors are seen in the present.
2. Dr. Bing develops the suit to fight the aliens.
3. The Bing suits are powered by crystanol which is obtained from the future.
4. Using the bing suits, the visitors are driven back.
5. The visitor mothership crashes and their leader is defeated. He's revealed to be Future Dr. Bing.
6. Future Dr. Bing says that because all the crystanol was used up, the future maple world became uninhabitable.

This is where it stops making sense. If all the crystanol is used up, then we can't go into the future and take it, because it doesn't exist there anymore. If we can't go into the future and take it, then the bing suits can't work. If the bing suits can't work, this means the visitor suits can never come to be, and that the future must still have plenty of Crystanol since no one traveled forward to take it. If there's plenty of crystanol, there's no reason for anyone to go back in time and try to live out-of-phase in the present. If there's no reason for anyone to go back in time, then it's impossible for us to have seen the visitors in the present at the start of the event. Therefore, there's no reason for the bing suits to be developed in the first place, no NEED for crystanol in the present, and no reason to go take it forward in the future. There is no problem and everyone lives happily ever after.

Future Doctor Bing also says, "When did the visitors ever attack you first!?" right before he sends you to the earliest point in the event's in-game timeline TO ATTACK FIRST. If he doesn't send you back in part 4 to kill yourself from part 1, then there would be no reason to assume the visitors were aggressive and no need for such a ridiculous plan to fight them off in the first place. So not only does the causality of events not line up under any sort of logic, but the "resolution" actually ends up ruining what little sense there was to be had out of it. from a storyline perspective, event is a total failure. As a game mechanics experiment, i'd say it was wildly successful. IMO it was also a failure from a gameplay perspective but that's more personal opinion.
