Should I get Skyrim for PS3?

ofcourse dude its totally worth it

actually you don't necessarily need to get the
Legendary edition right away. All it
comes with is the DLC, and you can
always just download the DLC later.
Choosing the regular edition and
picking up Batman: Arkham City is a
great choice. I think you're right to go
in that direction.

Skyrim DLC:

Dawnguard: Dawnguard is a great
DLC, and it has many tools for your
hero to use, as well as a great story,
but I would suggest getting this DLC
when you have done many things and
are looking for a new adventure.
Why? Because your townsfolk die in
this game, and when they die, they
don't come back. As soon as you
download this DLC, expect vampires to
attack, at random, which can enter
cities and attack you and anybody else
nearby after a nice nap. The DLC is
great, but the vampire attacks are
annoying. Expect to start the quest
now, or deal with random vampire
attacks and lots of re-loading until you
can save the day with no townsfolk
dying. How to make it harder for them
to kill the townsfolk? Easy! Just turn
up the difficulty. It doesn't guarantee
the people won't die, it just gives you
more time and allows them to
die...slower...

Hearthfire: This is a great choice even
at the very beginning. You get new
features that allow you to make a
house, move in your spouse, have a
family, customize your "lair," and
much more. If you like to Role-Play,
then Hearthfire is a solid choice that
gives you much more to do. It also
gives you more goals because of the
several things you need to collect in
order to make your house perfect.

The legendary edition will most likely
have all the DLC, which is nice to
have. Dawnguard is nice because of
the loot.
-Auriels Bow
-Aetherium Crown
-Zephyr
-Harkons Sword
-Dawnguard Rune Axe
Those are some off the loot included
in Dawnguard. The story is short, and
it kinda is bad, but actually tries to
have a plot. I would buy it because of
the loot and Vampire/Werewolf perks.

Dragonborn is the best DLC by far. It
lets you into solthstheim, an island
covered in ash, and you save it. Unlike
the rest of Skyrim, people here are
actually grateful for what you do. It's
nice to have that, when stupid Nords
in Skyrim call you milk-Drinker all the
time. The loot in Solthstheim is also
pretty cool, like the Champions
Cudgel and The Glass Bow of the Stag
Prince.

sorry to make it too long but I hope it helps :D
