why is it that i paid money for a game that corrupts the saves and wont save anymore? i mean i know bugs are part of a game but why are there so many in this one game?

Fallout 3 had all the same bugs, but not everyone has all these bugs.

has to do with the software used for the game, Gamebryo, I think. there would still be some issues like the bugs and glitches, but the major issues I'm sure reside in the outdated software that's been heavily modded and not repaired year after year.
