A little bird told me some games require data installation. Ill have a ps3 and I remember that Skyrim take an elephant place on computer, but I could play with disc...perhaps. OR, should I consider getting Oblivion?

What

I'm not sure what you're asking.
But yes, Skyrim is better than Oblivion.

i think he's asking how much space does it take to install skyrim on his ps3 harddrive.

i installed skyrim on my xbox, but i cant remember how much space it took tho. i still have lots of space on it tho.

also, i buy most single player games for xbox since most games you dont need to install to hard drive. and alot of games you
do need to install on ps3.

but if you have lots of space left on your ps3 it should be fine.
