Tried frequency analysis? I see multiple occurrences.

These repetitions can mean two things: 1) the algorithm used to encode/encrypt data is highly flawed, 2) the repeated parts mean the same thing, ie. they aren't part of another word but are a word an sich.
Important things: Capitals and numbers. Count the letters. Count the "words". Do you know the plaintext's language?

Guess english is the plaintext's language. I asked if you know anything, because there is a distinctive = sign at the end. That is the only non alpha-numeric character in the whole encrypted text, so I thought it was a distinctive mark of the algorithm used to encrypt it. |

Oh, the first crypttext is clearly base64. Unless they copied it's characteristics to mask another encryption. My post was about the "decoded" text from the base64.

Well I know that the decripted text is a alpha string that is in the continuation of the phrase "The Future...", so the decoded base64 string is not helpfull at all. |

Easy one.
You start with this:
Njg3NDc0NzA2MzZTNlA2UzZSNzM2UDYxNzM2ODczNl
A2MTczNjg3Nzc3Nzc2NDZTNzQ2UjZTNjg2NDZTNzQ3
MjZTNzM2UDYxNzM2ODc0NjU3Mzc0NzM2UDYxNzM2OD
IwDQo=
Obviously base64, so decrypt until you get this:
68747470636S6P6S6R736P617368736P6173687777
77646S746R6S68646S74726S736P61736874657374
736P61736820
Then you start messing around; let's try rot13 for example:
68747470636F6C6F6E736C617368736C6173687777
77646F746E6F68646F74726F736C61736874657374
736C61736820
Now that looks like some hexadecimal ASCII, right?
I'm not going to complete the whole challenge for you, because I already helped you enough with this. Just remember to keep messing around until you get something that makes sense.
@ Spy: how did you get that? :p

I accidentally encoded the data with base64 again -_-.
Disregard my posts.
