I cut my teeth on 6502 on an Acorn Atom and a home built hex machine 
built from Elektor magazine before moving onto BASIC, Forth (Speccy 
White Lightning) Z80, Pascal, C, C++, Java and now Python.

There is a trade-off as you move from assembler to OOP; you delegate 
more of the mindless donkey work to the compiler/interpreter which makes 
things easier and less prone to things like memory clashes but you also 
create code with a lot less efficiency.

I use OOP almost exclusively now except for some scripting stuff and for 
complex systems it works fine (although "Hello World" can be several 
megabytes depending on the language you are using).

Why use it? Extensibility - if you want another bad guy just instantiate 
a new object and the routines and variables are there.
Inheritance - If you need to create a new type of bad guy just extend 
the generic BadGuy Object and override/add the relevant routines it 
makes for a common codebase, a logical data structure and easier 
development.
Interfacing with the hardware. With the speccy you could easily 
interface directly with the video memory or the sound. Moving a 
character was a matter of changing some bits in memory. Computers have 
advanced massively (some would say in a backwards direction) and it is 
rare for you to be able to directly interface with the hardware, now you 
have to go through abstraction layers and various interfaces and 
libraries that are all geared toward OOP. You could write stuff on 
assembler but the first things you would need to do would be to write 
all the interface libraries.

I was a procedural programmer for ages but then I took an Open Uni 
course on OOP, it was tough changing my way of thinking from procedural 
to OOP but it made sense (even if all through the course they were 
talking about customers, account numbers and account balance and I was 
translating it in my head to character name, hit points and gold)

Bottom line - if you want to learn it then learn it otherwise don't. 
Unless you need OOP I would ignore it.
