I thinks its both.you can buy them,but you can also pick them up around places and off dead people

For horses you can buy them or you can find the wild horses that are around the place and break them in to use them

and the third one, it think this game should hold you.it looks really good..but then i didnt get bored of gta quite as fast as you did.i lasted longer liking it

sony are being ridiculous they just tell you that they have updated the computer since we bought them(thats if you got it like when it first came out) but they dont seem to do anything about the fact that they first batch was faulty..they just leave it as your loss...

ye this happened to me as for getting the game out the only way i could do it was to just take the top off it and get the game out..
